First add 15 and 45. Then find the factors. 15+45=60 The factors of 60 are 1, 2, 3, 4, 5, 6, 10, 12, 15, 20, and 30.
5(x + 3)
(2x - 5)(2x - 3)
3(3x + 5)
3 is a factor and dividing by 3 gives x + 15 = 8x
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.
Anything that isn't 1, 3, 5, 15
x2 + 8x + 15 = (x + 3)(x + 5)
x2 + 8x + 15 = (x + 3) (x + 5).
2x2+13x+15 = (2x+3)(x+5)
First add 15 and 45. Then find the factors. 15+45=60 The factors of 60 are 1, 2, 3, 4, 5, 6, 10, 12, 15, 20, and 30.
(x+3)(x+15)
It is; 5(b+3)
15(p + 4)
5(x + 3)
