Question

Factorize using appropriate identity 16x^2-9y^2​

Answer 1

Use:

Use:(a+b)(a-b) = (a)^2 + (b)^2

Use:(a+b)(a-b) = (a)^2 + (b)^2(4x)^2-(3y)^2

Use:(a+b)(a-b) = (a)^2 + (b)^2(4x)^2-(3y)^2(4x+3y)(4x-3y)

Use:(a+b)(a-b) = (a)^2 + (b)^2(4x)^2-(3y)^2(4x+3y)(4x-3y)Hence, solved

Answer 2

Answer:

(4x)^2 - (3y)^2 = (4x + 3y) (4x - 3y)
