Question

36(a - b)- 25 (a + b)2​

Answer 1

Answer:

36(a-b)² - 25(a+b)²

= 6²(a-b)² - 5²(a+b)²

= [6(a-b)]² - [5(a+b)]²

using a² - b² = (a-b)(a+b)

[6(a-b) + 5(a+b)] [6(a-b) - 5(a+b)]

= (6a - 6b + 5a + 5b) (6a - 6b - 5a - 5b)

Answer 2

STEP

1

:

Equation at the end of step 1

(36 • (a + b)) - 25 • (a - b)2

STEP

2

:

Equation at the end of step 2

36 • (a + b) - 25 • (a - b)2

STEP

3

:

3.1 Evaluate : (a-b)2 = a2-2ab+b2

Final result :

-25a2 + 50ab + 36a - 25b2 + 36b
