Rearrange the polynomial:
a^2–2ab+b^2 - c^2
((a-b)(a-b))-c^2
(a-b)^2-c^2
Set x =a-b and y=c. The formula becomes
x^2-y^2
factoring this polynomial, we get
(x+y)(x-y)
Substituting back, we get:
(a+b+c)(a+b-c)
Let’s multiply it out to check:
A^2 -ab ac
- ab B^2 -bc
-ac bc -c^2
Answer:
(a + b + c)(a + b - c)Step-by-step explanation:
Use of formula:
(a+b)^2 = a^2 + 2ab + b^2a^2 - b^2 = (a + b)(a - b)Factoring the expression
a^2 + b^2 – c^2 + 2ab =(a^2 + 2ab + b^2) - c^2 = (a + b)^2 - c^2 =(a + b + c)(a + b - c)I need help and quick please

Write the number in expanded form: Three hundred twenty-six thousand, five hundred eight and nine hundredths?
Answer: 300,000 + 20,000 + 6,000 + 500 + 8 + 0.09
The required expanded form of three hundred twenty-six thousand, five hundred eight and nine hundredths, 300,000 + 20,000 + 6,000 + 500 + 80 + 0.09.
Given that,
To determine the expanded form: Three hundred twenty-six thousand, five hundred eight and nine hundredths.
A number system is described as a technique of composing to represent digits. It is the mathematical inscription for describing the numbers of a given set by using numbers or other characters in a uniform method. It delivers a special presentation of every digit and describes the arithmetic structure.
Here,
Three hundred twenty-six thousand, five hundred eight and nine hundredths = 326580.09
The expanded form of a number is the sum of the digit with the intrinsic value of the digit placed in the number,
Expanded form = 300,000 + 20,000 + 6,000 + 500 + 80 + 0.09.
Thus, the required expanded form of three hundred twenty-six thousand, five hundred eight and nine hundredths, 300,000 + 20,000 + 6,000 + 500 + 80 + 0.09.

O Report an
® Quit asses
Answer:
-21
Step-by-step explanation:
I used the backward method
She adds 8 to get 5.
So we start with 5 and subtract 8
5-8 = -3
She divides by 7 but since we are using the backwards method, we have to multiply.
-3*7= -21
After that, we can check our answer
Krutika was thinking of -21
-21/7= -3
-3+8= 5
-21 is the answer

If the value the discriminant is exactly 0, what is true about the graph of the quadratic equation?
The truth about the graph of the quadratic equation would be the vertex of the parabola connects the x-axis when the value of the discriminant is exactly zero.
What is a quadratic equation?The quadratic equation is defined as a function containing the highest power of a variable is two.
When discriminant D of a quadratic equation,
D = 0
Roots are equal and real
D > 0
Roots are real and different
D < 0
Roots have not existed.
When the discriminant is zero, there is only one real root to the quadratic equation. In other words, only the vertex of the parabola connects the x-axis. The vertex is the parabola's base.
Therefore, the truth about the graph of the quadratic equation would be the vertex of the parabola connects the x-axis when the value of the discriminant is exactly zero.

Given g(c) = f(x) + k, enter the value for k that transforms the function f into g?
k =
Translation involves changing the position of a shape or line or point.
The value of k is -3
The given parameter is:
[tex]\mathbf{g(x) = f(x) + k}[/tex]
From the attached graph, we can see that the line of f(x) is shifted down by 3 units to form g(x).
This means that:
[tex]\mathbf{g(x) = f(x) - 3}[/tex]
By comparing: [tex]\mathbf{g(x) = f(x) - 3}[/tex] and [tex]\mathbf{g(x) = f(x) + k}[/tex]
We have:
[tex]\mathbf{k = -3}[/tex]
Hence, the value of k is -3

If a translation is described as (x -5, y), how has the original image changed?
Answer:
It moves the x value 5 units to the left.
Step-by-step explanation:
"x - 5" means that we are subtracting 5 to whatever x value we are given. The "y" value doesn't change.
Since we are subtracting to the x value, we are going to move left 5 units.
Let's say we had the point (5, 5).
If we use the translation rule;
(5 - 5, 5)
(0, 5)
We moved the x value 5 units to the left.
Best of Luck!
