3x2 - 15x + 42 = 3*(x2 - 5x + 14) which cannot be factorised further.
The GCF is 15x^2y^2
15x minus 8=minus 180 3x+8=24
6xsquared minus 26x minus 5 over 3xsquared minus 15x
you just add 6x+9x to get 15x then minus 25 from 18 to get -7 thus the answer will be 15x-7
2x^3 - 3x^2 + 4x - 3
5x^3(3x + 2)
6/5x = 18/15x 2/3x = 10/15x 18/15x - 10/15x = 8/15x
The GCF is 15x.
-15x=-5*3x+2 -15x=-15x+2 +15x +15x ----------------- 0=2
It is: 5x(x-3)
14x2 + 15x + 4 = (7x + 4)(2x +1)
x2+15x+14 = (x+1)(x+14)
