Question

2. Multiply and verify the result for the given values.
(a) (8a + 76) (64d – ab + b); a = 1, b = -2​

Answer 1

Answer:

-10,752

Step-by-step explanation:

(8a+76) (64b-ab+b)

8a(64b-ab+b)+76(64b-ab+b)

512ab-a^2+ab+4864b-76ab+76b

512ab-76ab+ab+4864b+76b-a^2b

437ab+4940b-a^2b

a=1,b=2

437(1)(-2)+4940(-2)-(1)^2(-2)

=-10,752
