Find the roots of this polynomial: \({x^2} - 9x + 8\).

Explanation

Questions that say, “solve the given polynomial” and “find the roots of the polynomial” mean the same thing. The first step would be to factor out the polynomial:
\(x^{2}−9x+8=(x−1)(x−8)\).
Then, equate each factor to zero.
(x−1)=0;x=1.(x−8)=0;x=8.
The roots of the given polynomial are x=1 or x=8.
