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

$\rm x = \dfrac{-b\pm \sqrt{b^2-4ac}}{2a}$

The solutions are given below.

$\rm x = \dfrac{-3 \pm \sqrt3 \iota }{2}$

Then

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

$\rm x = \dfrac{-6\pm 6\iota}{4}\\\\x = \dfrac{-3\pm 3 \iota}{2}$

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

$\rm x = \dfrac{-3\pm \sqrt{39}\iota}{2}$

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

$\rm x = \dfrac{-3\pm \sqrt3\iota}{2}$

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

$\rm x = \dfrac{-6\pm 2\sqrt{3}}{4}\\\\x = \dfrac{-3\pm \sqrt3 }{2}$

More about the quadratic equation link is given below.

What is the cross section created when a vertical slice is made perpendicular to the 2 bases of a triangular prism?

Katena32 [7]

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.
