Web2. I've to solve the following polynomial inequality. x 2 − 6 x + 11 > 0. By using quadratic formula, I got the value of x as below. 6 ± − 8 2. These are imaginary roots and the … WebThe two known roots have sum 2, so the missing root must be − 2. If the leading term of the polynomial has coefficient 1, then the product of its roots gives the free term. Your polynomial has real coefficients; if 1 − 2 i is a root, then so is 1 + 2 i. Thus, we arrive to 10 = ( 1 − 2 i) ( 1 + 2 i) a, where a is the real root. did george harrison beat his wife https://petersundpartner.com
