  1. 2x^2(x-3)+12x(3-x)-18(x-3)
    2x^2(x-3)-12x(x-3)-18(x-3)
    (x-3)(2x^2-12x-18)
    2(x-3)(x^2-6x-9)
    2(x-3)(...wondering if you had a typo on the -18. If it was +18, it would have been simple..
    2(x-3)^3
    as it is,

    x=3+-sqrt(18)
    2(x-3)(x-3-3sqrt2)(x-3+3sqrt2)

    I'm not sure how to factor 3x^3-12x^2+3x. I tried separatring the 3x so that 3x(x+1)(x-4, but I got -3x^3+-12x^2-3x^2+12x. Can you show me where I went wrong and how to properly factor this? Is there a general rule or tip for this

    solve this please....help me....12x(squared)+7x-10 Do you wish to factor this trinomial? If so, the factors are: (4x + 5)(3x - 2) You can use the FOIL method to check. If this is supposed to be an equation: 12x^2 + 7x - 10 = 0

    How do you factor 4x(squared)+12x+40? Thanks! 4x2+12x+40= 4(x2+3x+10) Is there any way to get it like ( ) *( )? I don't think the term within the parentheses can be factored. The only factors of 10 are 10*1 and 5*2 and neither of
