Question

How do I completely factor x^4+8x^3-20x^2

Answer 1

you can factor out a common factor of \(x^2\) and start with
\[x^2(x^2+8x-20)\]

Answer 2

then maybe you can factor the second part
i suck at factoring but i think this one is more or less easy

Answer 3

now take common factors from the brackets inside and simplify...
