Question

Factor

Answer 1

\[-18x ^{4}+18x ^{3}+12x-12\]

Answer 2

well start by grouping in pairs

(-18x^4 + 18x^3) + (12x - 12)

remove common factors from each pair... what do you get

Answer 3

\[\frac{ -18x ^{4} }{ -18x ^{3} } \]

Answer 4

\[\frac{ +18x ^{3} }{ -18x ^{3} }\]

Answer 5

(x+1)
?

Answer 6

well not quite -18x^3 is a common factor

and in the other pair you get 12

so its

-18x^3(x - 1)+ 12(x -1)

which gives

(-18x^3 + 12)(x - 1)

so take out -6

and you get

-6(3x^3 + 2)(x - 1)

and I'd say that's the answer

Answer 7

Oh, thank you :)

Answer 8

oops the final answer should be

-6(3x^3 - 2)(x -1)
