Question

When a = 0, b = –1 find the value of the expression
a^2+2ab+2-ab

Answer 1

Given :

• a^2 + 2ab + 2 - ab, a = 0 & b = - 1

To Find :

• The value of the expression

Solution :

a^2 + 2ab + 2 - ab

= a^2 + ab + 2

= 0^2 + (0)(-1) + 2

= 0 + 0 + 2

= 2

∴ The value of the expression is 2.

Answer 2

0^2 + 2(0)(-1) + 2 -(0)(-1)
0 + 0 + 2 +0
= 2
