x2 + 5x + not really sure what that extra plus is for... this is the most you can factor it... x(x + 5)
(5x - 2)(x - 5)
5x squared plus 33x plus 18 = (5x + 3)(x + 6) x = -6, -3/5
x(2x + 5)
5(x^2 + 9)
5(x^2 - 4xy + 2y^2)
5
5(x - 5)(x + 5)
5x^2(4x - 5)(5x + 11)
2x2 + 5x = x*(2x + 5)
You can factor a five out of 15 plus 5x. Therefore, 15 plus 5x factors out to 5(3+x). Hope it helps :)
(x - 5)(5x - 7)
