Question

use suitable property to get product:(a^2+b^2)(-a^2+b^2)

${a}^{2} {-b}^{2} = (a + b)(a - b)$
please answer fast...​

Answer 1

Answer:

(b^4-a^4)

Step-by-step explanation:

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

so taking a = b^2 and b = a^2

for (a^2+b^2)(-a^2 + b^2)

[(-a^2 + b^2) can be written as (b^2-a^2)]

we get (b^4-a^4)
