The complete factor of the polynomial 9xy + 36x − 10y − 40 is (9x − 10) (y+4). Then the correct option is C.

What is polynomial?

Polynomial is an algebraic expression that consists of variables and coefficients. Variable are called unknown. We can apply arithmetic operations such as addition, subtraction, etc. But not divisible by variable.

Factor completely 9xy + 36x − 10y − 40.

Take 9x common from the first two terms and -10 from the last two terms. we have

9xy + 36x − 10y − 40

9x (y + 4) − 10 (y + 4)

Take y+4 common, then we have

(9x − 10) (y + 4)

The complete factor of the polynomial 9xy + 36x − 10y − 40 is (9x − 10) (y+4). Then the correct option is C.
