Question

Find All Roots Of The Equation;

x^3 + x^2 + 4x + 4= 0

I just need help explaining how to solve the problem.

Answer 1

Explanation:

you would solve by grouping the first two terms together and the last two terms together. (x^3+x^2)(+(4x+4)=0. you would factor each one and get x^2(x+1)+ 4(x+1)=0. the final outcome is (x^2+4)(x+1)=0. this is how you find the roots of this equation

sorry if this answer is wrong
