Question

Which of the following shows factoring of polynomials with difference of two squares? * 1 point A. 4a^2 – b^2 = (2a+b)(2a-b) B. x^-2xy+y = (x-y)(x-y) C. 25m^4+15m^3 = 5m^2 (5m^2+3m) D. x^2-x-2 = (x-2)(x+1​

Answer 1

Answer:

vhhhhvvhvb bbbbbbbbkkkk

Answer 2

A) 4a^2-b^2= (2a+b) (2a-b)

We can show polynomial as the difference of two square when the expressions are a perfect square.

Note that the leading coefficient that is coefficient of maximum degree digit does not have to be equal to 1 if we want to express it as difference of two squares.

In this option, 4a^2 – b^2, (4a^2) and b^2 both are. perfect squares, therefore we can express this as the difference of two squares, that is (2a)^2 - (b) ^2= (2a+b) (2a-b)
