Q. −983 is a root of f(x)=x2−28,812. 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 −983 is a root, the other root must also be −983 because the coefficients of the polynomial are real numbers, and non-real roots of polynomials with real coefficients always come in conjugate pairs.
Using 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=−28,812.
Calculate product: The product of the roots is (−983)×(other root)=−28,812.
Find other root: Divide −28,812 by −983 to find the other root: (other root)=−983−28,812.
Simplify expression: Simplify the expression: (other root)=2943.
