Math HELP PLEASE!!!?

Question

Factor completely
1. 6x^3-2x^2 - 4x
2. 6f^4 - 24f^2
3. 24gh-18g^2 - 8h^2
4. m^2 + 6n - 9n^2 - 2m

Answer 1

1. 2x(3x^2-x-2)
=2x(3x^2-3x+2x-2)
=2x(x-1)(3x+2)
2. 6f^2(f^2 -4)
=6f^2(f-2)(f+2)
3. -2(9g^2-12gh+4h^2)
= -2(3g-2h)^2
4. m(m-2)-3n(3n-2)

Answer 2

1) 2x(3x^2 -x -2) = (2x)(3x+1)(x-2)

2) 6f^2(f^2 -4) = 6f^2(f+2)(f-2)

3) -2(-12gh + 9g^2 + 4h^2) = -2(3g-2h)(3g - 2h)

4) m(m-2) - 3n(3n - 2)
