What is the completely factored form of 25x4 – 16y2?

(5x4 4y)(5x – 4y)

(5x3 4y)(5x2 – 4y)

(5x2 4y)(5x2 – 4y)

25x4 – 16y2

Step-by-step explanation:

has the form known as a difference of squares. It factors into (a+b)(a-b). To find a and b you take the square root.

The factored for is (a+b)(a-b).

In this case, it is

the dimensions are:

step-by-step explanation:

we want to find the dimensions of a rectangular box with volume of

we factor to obtain;

we rewrite the rightmost factor to obtain;

recall that:

we apply difference of two squares formula to obtain;

hence the dimensions are
