factor these problems and can u please show the work.
6) 8x2 + 8x – 6
8x^2 + 12x - 4x - 6
4x(x+3) - 2(x+3)
(x+3)(4x-2)
2(x+3)(x-1)
=================
7) 12y3 + 28y2 + 8y
4y(3y^2 + 7y + 2)
4y(3y^2 + 6y + y + 2)
4y[3y(y+2) + (y+2)]
4y(y+2)(3y+1)
==================
8) 9x3 – x
x(9x^2-1)
x(3x-1)(3x+1)
=================
