5(x + 3)
x2-8x+15 = (x-3)(x-5)
3(3x + 5)
3 is a factor and dividing by 3 gives x + 15 = 8x
15 is not a factor of 100.
The highest common factor of 15 and 45 is 15
You can factor a five out of 15 plus 5x. Therefore, 15 plus 5x factors out to 5(3+x). Hope it helps :)
The greatest common factor of 10y plus 15 is 5.
x2 + 8x + 15 = (x + 3)(x + 5)
x2 + 8x + 15 = (x + 3) (x + 5).
2x2+13x+15 = (2x+3)(x+5)
(x+3)(x+15)
It is; 5(b+3)
15(p + 4)
5(x + 3)
(x + 15)(x + 5)
(2x+1)(2x+3) when factored
