Best ResponseYou've already chosen the best response.0x(x^2  12x + 32) = 0 x(x  4)(x  8) = 0 x = 0, 4, 8

Best ResponseYou've already chosen the best response.0divide by x, then solve the remaining quadratic. x^212x+32=0=(x8)(x4) x=8,2

Best ResponseYou've already chosen the best response.0regan, you have to account for the fact that you divided by x, meaning that x could be zero as well you see this is true if you plug zero back into the equation, you'll get 0 = 0, which is true, hence, x = 0 is also a solution to this equation

Best ResponseYou've already chosen the best response.0x(x^2  12x + 32) = 0 x(x  4)(x  8) = 0 do you get this part?

Best ResponseYou've already chosen the best response.0after that part you just set each part equal to 0 so x = 0 x  4 = 0 x  8 = 0 solve for each x x = 0, 4, 8

Best ResponseYou've already chosen the best response.0x(x^2  12x + 32) = 0 this part? i factored out the x to get to this part x(x  4)(x  8) = 0 you have to factor do you know how to factor?

Best ResponseYou've already chosen the best response.0Ya i know how 2 factor i jus dont get how x factored 12 and got 4?

Best ResponseYou've already chosen the best response.0factor out the x x(4x^2  1) = 0 x = 0 4x^2  1 = 0 4x^2 = 1 x^2 = 1/4 \[x = \pm 1/2\]

Best ResponseYou've already chosen the best response.0i factored x out of x^312x^2+32x=0 to get x(x^2  12x + 32) = 0 than i factored INSIDE the parenthesis to get x(x  4)(x  8) = 0 go to this site http://tutorial.math.lamar.edu/Classes/Alg/Factoring.aspx it teaches you how to factor
