3x2 + 15x + 6 = 3*(x2 + 5x + 2).
There are no further rational factors.
-15x2+5x=-5x(3x-1)
5x(3x + 1)
It is: 3x*(x+7)
If that's -18y2, the answer is (3x - 2y)(x + 9y)
6x2 + 10x = 2x*(3x + 5)
-15x2+5x=-5x(3x-1)
3(x + 4)(x + 1)
5x(3x + 1)
3x3+15x2+18x = 3x(x2+5x+6) = 3x(x+2)(x+3)
3x
15x squared plus eleven
3x(56x2-15x+1)
3x
18x2 + 15x + 2 = (3x + 2)(6x + 1)
It is: 3x*(x+7)
(3x - y+ 2)(3x + y + 2)
NOTE: xx can be written as x^2 i.e. x squared 3x^2 + 16x + 5 = 3 x^2 + x + 15x + 5 (Since 16x = x + 15x) = x ( 3x + 1 ) + 5 ( 3x + 1 ) = ( x + 5 ) ( 3x + 1 ) Therefore the factors are ( x + 5 ) and ( 3x + 1 )
