Factor p(x) = 3x^3 – 12x
Take out a GCF (greatest common factor, which is 3x) factor what is left, (x^2 - 4)Please respond if you understand, or if you need more help!
remmberab-ac=a(b-c)a=GCFso factor3x^3=3xxx12x=223xgcf=3*x=3x3x(x^2)-3x(4)=3x(x^2-4)we can also factor the inner furtherremember that a^2-b^2=(a+b)(a-b)so(x^2-4)=x^2-2^2=(x+2)(x-2)fully factored is3x(x+2)(x-2)
