For this case we have the following factorized expression:

(2y-9) (2y-9)

Applying distributive property we have:

(2y) (2y) - (2y) (9) - (9) (2y) + (9) (9) =\\4y ^ 2-18y-18y + 81 =

We add similar terms taking into account that: Equal signs are added and the same sign is placed.

4y ^ 2-36y + 81

17. Let f(x) = 2x2 + 5x + 6 and g(x) = 3x2 + 4x – 10.<br> a Find f(x) + g(x)<br> b. Find f(x) – g(x)
nalin [4]

Step-by-step explanation:

f(x)+g(x)=(2x^2 + 5x +6) + (3x^2 +4x - 10)

Combine like terms

5x^2 + 9x -4

f(x)-g(x)=(2x^2 + 5x +6) - (3x^2 +4x - 10)

Distribute the negative

(2x^2 + 5x +6) + (-3x^2 -4x + 10)

Combine like terms

-x^2 +x +16
