You can factor a five out of 15 plus 5x. Therefore, 15 plus 5x factors out to 5(3+x).
Hope it helps :)
5(x + 3)
Since 5 is a factor of 15, it is automatically the GCF.
5(x + 3)
15
It is: 5x
(5x - 3)(3x + 5)

30 + 5x = 15 + 10x 30 = 15 + 5x 15 = 5x x = 3
15x2+16x-15 = (3x+5)(5x-3) when factored
5x
5x + 15 = 5(x + 3)
-15x2+5x=-5x(3x-1)
