Does anyone know the answer to these two problems?

8) -8, -9

9) 4,

Step-by-step explanation:

8) x² + 12x + 27

Solutions of a polynomial means the values of such that the polynomial becomes zero. .

We use the following formula to determine the solutions of a quadratic equation of the form:

In this equation,

Substituting in the formula, we have:

Taking 2 common outside we get:

Therefore, we get two solutions viz, x = -3, -9.

9) 2x² - 9x + 4 = y

X- intercepts of a polynomial means the value of x such that y = 0. It means the roots of the polynomial.

Solving the equation using the formula above, we get:

The values of x = 4, .

Hence, the answer.
