Solve the question mark (?). Represent x as the value of the question mark

(-1) (-2) (x) (-4) (-5) = -120

(2) (x) (20) = -120

40x = -120

(shaded 40)x / (shaded 40) = -120/40

x = -3

Check:

(-1) (-2) (-3) (-4) (-5) = -120

(2) (-3) (-4) (-5) = -120

(-6) (-4) (-5) = -120

(24) (-5) = -120

The missing number is -3

$2x^{2}$ is a monomial (since it is all connected by multiplication) and since it is in the degree of 2, that makes it a quadratic.

-2 is a constant (since it doesn't have variables) and it is a monomial (since it is all connected by multiplication)

3x-9 is a binomial (since it has two terms, not connected by multiplication) and since it has x in the power of 1, that makes it a linear equation.

Finally, $-3x^{2}$ -6x + 9 is a trinomial (since it has 3 terms connected by either addition or subtraction) and since the degree of the polynomial is 2, that makes it a quadratic.
