Question

Also show how you got the answer pls

Answer 1

m² + 7m - 9

Explanation:

`(m^3+16m^2+54m-81)/(m+9)`

setting up the synthetic division

- 9 | 1 16 54 - 81

↓ - 9 - 63 81

-------------------------

1 7 - 9 0 ← remainder

quotient is m² + 7m - 9

since the remainder is zero then (m + 9) is a factor of the polynomial
