Question

PLEASE HELP!!! URGENT!! NEED HELP ASAP!!
(x^2-2x)^2-14(x^2-2x)-15

Answer 1

this is an equation that is reducible to a quadratic

so let

\[u = x^2 - 2x\]

then the equation becomes

\[u^2 - 14u - 15\]

which factors to

\[(u - 15)(u + 1)\]

now do the reverse substitution for u and you get

\[(x^2 - 2x - 15)(x^2 - 2x + 1)\]

and you should be able to factor these...
