Question

Find the roots of each polynomial equation X^3-2^2+5x-10=0.

Answer 1

Answer: x^3 - x^2 +5*(x - 2) = 0 <=> ( x^2)*(x - 2) +5*(x - 2) = 0 <=> (x - 2)*(x^2 + 5) = 0 =>

x = 2

Explanation:

Answer 2

x^3 - x^2 +5*(x - 2) = 0 <=> ( x^2)*(x - 2) +5*(x - 2) = 0 <=> (x - 2)*(x^2 + 5) = 0 =>
x = 2;
