Y=3x+5
This type of statement is called a difference of squares. If you see an equation in the form:a2 - b2then it is also equal to:(a + b)(a - b)In this case 9x2, and 25 are both perfect squares. 9x2 is equal to (3x)2 and 25 is equal to 52, so the that statement can be factored out as:(3x - 5)(3x + 5)
3x^2
