Question: Is my solution correct? Use the Factor Theorem to find all real zeros for the given polynomial function and one factor. For a square root

Is my solution correct?

Use the Factor Theorem to find all real zeros for the given polynomial function and one factor. For a square root of a number, enter sqrt followed by the number in parentheses. For example, enter sqrt (2) for v2. f (x) = x' +3x2 - 7x-21; x+3 What zero corresponds to the factor x + 3? X = -3 -3 What is the other positive zero? X = sqrt (7) V7 What is the remaining zero? X = -sqrt (7) -V7
