8x2 + 15 + 26x = 8x2 + 26x + 15 = 8x2 + 20x + 6x + 15 = 4x(2x + 5) + 3(2x + 5) = (2x + 5)(4x + 3)
14x2 + 29x - 15= 14x2 + 35x - 6x - 15= 7x(2x + 5) - 3(2x + 5)= (2x + 5)(7x - 3)
15
x + 3
4 multiplyed by a number (Variable) plus 5 multiplyed by a number (V) equals 15 4v + 5v = 15 15/5 = v 15/4 = impossibility >_< Sorry :~) v = ImPoSiBiLiTy
12x2 - 28x - 15= 12x2 - 18x - 10x - 15= 6x(2x - 3) - 5(2x - 3)= (6x - 5)(2x - 3)
It will be: 6x2 +8x -15
-3 and 4x2 - 5x - 5 are the factors of -12x2 + 15x + 15.
5x + 15 = 28xSubtract 5x from each side:15 = 23xDivide each side by 23:15/23 = xThat's about 0.652 (rounded).
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)
15x2 + 2x - 56 = 15x2 + 30x - 28x - 56 = 15x(x + 2) - 28(x + 2) = (15x - 28)(x + 2)
(x+3)(x+15)
