F(x) = 2x^2 - x
if x=-3
f(-3) = (2*(-3)^2) - (-3)
f(-3) = (2*9) + 3
f(-3) = 18 + 3
f(-3) = 21
The quadratic equation which matches given solution is x² + 3x + 3 = 0. Then the correct option is C.
<h3>What is a quadratic equation?</h3>
It is a polynomial that is equal to zero. Polynomial of variable power 2, 1, and 0 terms are there. Any equation having one term in which the power of the variable is a maximum of 2 then it is called a quadratic equation.
We know that the formula

The solutions are given below.

Then
1) 2x² + 6x + 9 = 0, the zeroes of the equation will be

2) x² + 3x + 12 = 0, the zeroes of the equation will be

3) x² + 3x + 3 = 0, the zeroes of the equation will be

4) 2x² + 6x + 3 = 0, the zeroes of the equation will be

Imagine slicing a triangular prism, perpendicular to the two bases.
You would basically just be lopping off some congruent triangle from each base.
The now-exposed inside of the prism would be a rectangle.
