How do you Factor 2x^4+x^2-6
(2x^2-3)(x^2+2)this is the answer
use u subsitutionu=x²2u²+u-6now do ac method2 times -6=-12what 2 numbers multiply to -12 and add to get 1-3 and 4split the middle temr like that2u²+4u-3u-6group(2u²+4u)+(-3u-6)factor2u(u+2)+(-3)(u+2)undistribue(2u-3)(u+2)u=x²(2x²-3)(x²+2)
