Write as a product: 16−(3−4b)^2

If you help and get it right, I'll try to give you an extra ten points.

Step-by-step explanation:

16 = 4^2 What you get is then  a difference of squares.

(4 - (3-4b)) * (4 + (3 - 4b)) Remove the brackets.

(4 - 3 + 4b) * (4 + 3 - 4b)  Combine like terms.

(1 + 4b)(7 - 4b)

answer: the common difference is -0.10
