Question

If a = 2, b = –2, find the value of (2a2b + 2ab2 +ab)

Answer 1

Answer:

2a²b+2ab²+ab

2*4*-2+2*2*4+2*-2

-16+16-4

-4 is the right answer

Answer 2

Answer:

-4

Step-by-step explanation:

(2a²b + 2ab² + ab)

a = 2, b = -2

=> 2(2)²(-2) + 2(2)(-2)² + 2(-2)

=> -4(4) + 4(4) + (-4) => -4(4) + 4(4) - 4          (Minus and minus combine to become plus)                  

=> -16 + 16 - 4 => 0 - 4 => -4
