Question

Usingasuitableidentity,findtheproduct:

1.(a2+b2)(-b2+a2)​

Answer 1

Answer:

it is in the form of (a+b)(a-b) so it can be written as a square -b square where a and b are a square and b square respectively

Answer 2

Answer:

(2a + 2b)(2a-2b)

Step-by-step explanation:

1) (a2 + b2)(-b2+ a2)

= a2(-b2+ a2) + b2(-b2+ a2)

= -4ab + 4a^2 - 4b^2 + 4ab

= 4a^2 - 4b^2

= (2a)^2 - (2b)^2

= (2a + 2b)(2a - 2b)
