part a: factor x2y2 + 6xy2 + 8y2. show your work. (4 points)

part b: factor x2 + 8x + 16. show your work. (3 points)

part c: factor x2 − 16. show your work. (3 points)

The factorization of all the parts are :

Part A :

Part B :  

Part C :  

Step-by-step explanation:  We are given to factorize the following quadratic polynomials :

Part A : Factor x²y² + 6xy² + 8y².  

Part B : Factor x² + 8x + 16.

Part C: Factor x² − 16.

We will be using the following factorization formulas :

The factorization of all the parts area as follows :

Part A :

We have

So,

Part B :

We have

So,

Part C :

We have

So,

Thus, all the parts are factorized.

look at the picture.

y-intercept for the function on a picture is 4 → point (0, 4).

y-intercept for the function

is for x = 0. substitute:

y-intercept is 8 → point (0, 8).
