Question

Use factoring to solve the polynomial equation:423 + 422 – 482 = 0Answer:

Answer 1

$\begin{gathered} We\text{ have 3 roots because we have a cubic equation} \\ 4x^3+4x^2-48x=0 \\ 4x\cdot(x^2+x-12)=0 \\ 4x\cdot(x-3)\cdot(x+4)=0 \end{gathered}$

Now, let's analyze each factor

4x=0

x=0

x-3=0

x=3

x+4=0

x=-4

Answer

x=0, x=3, x=-4
