Answer 2

Answer:

(6x-7)(6x-7)= 36x^2-84x + 49 (sum of inner product(-42x) and outer product(-42x)=-84x

FIND THE PRODUCT

(8x-3z)(8x+3z)= 64x^2 -9z^2 (sum of inner product(-24x) and outer product(24x) = 0

USING THE FORMULA (a+b)(a-b)=a^2-b^2 to multiply

(9x-7)(9x+7) = 81x^2 - 49 (sum of inner product
