a2 - b2 = (a - b)(a + b)
a2 - b2 = (a - b)(a + b)
15y4-39y3+18y2
a2 - b2 = (a + b)(a - b).
It is the difference of two squares which is: (x+2y)(x-2y)
The formula to factor the difference of two squares, a2 - b2, is (a + b)(a - b).
The formula is: A2 - B2 = (A + B) (A - B)
a2 - b2 = (a - b)(a + b)
a2 - b2 = (a - b)(a + b)
There is a formula for the difference of two squares. The sum of two squares doesn't factor.
15y4-39y3+18y2
a2 - b2 = (a + b)(a - b).
It is the difference of two squares which is: (x+2y)(x-2y)
