Q. −793 is a root of f(x)=x2−18,723. Find the other roots of f(x).Write your answer as a list of simplified values separated by commas, if there is more than one value.
Given root information: Since −793 is a root, the other root must also be −793 because the coefficients of the polynomial are real numbers, and non-real roots of polynomials with real coefficients always come in conjugate pairs.
Product of roots: To find the other root, we can use the fact that the product of the roots of a quadratic equationax2+bx+c=0 is ac. Here, a=1 and c=−18,723.
Calculate other root: The product of the roots is (−793)×(other root)=−18,723.
Simplify expression: Divide both sides by −793 to find the other root: (other root) = −793−18,723.
Rationalize denominator: Simplify the expression: (other root)=79318,723.
Calculate final answer: Rationalize the denominator by multiplying the numerator and denominator by 3: (other root) = 79×318,7233.
Calculate final answer: Rationalize the denominator by multiplying the numerator and denominator by 3: (other root) = 79×318,7233.Calculate the simplified value: (other root) = 23718,7233.
Calculate final answer: Rationalize the denominator by multiplying the numerator and denominator by 3: (other root) = 79×318,7233.Calculate the simplified value: (other root) = 23718,7233.Divide 18,723 by 237 to get the final answer: (other root) = 793.
