Question

A = 2, b = -2 find the value of a2+b2a

Answer 1

Answer:

The two expressions, a2 + 2ab + b2 and c2 + 2ab, both represent the total area of the large square. Hence, they must be equal to one another. a2 + 2ab + b2 = c2 + 2ab Each side of this equation represents the area of the large square.

Answer 2

Answer:

(a)² + b²a

(2)² + (-2)² x 2

4 + 4 x 2

4 + 8

12
