Answer:

Step-by-step explanation:
For example, we'll use this quadratic equation.

To understand how to plug it into the formula we need to know what each term represents.

So the equation above would be put into the formula like this.

Then we would solve

Now, the equation will branch off into one that solves when addition and one when subtraction.

So x={-3, -2} (-3 and -2)
They are not all squares because a rhombus has all sides of equal length, but NO right angles. A square is a rhombus WITH right angles.
Hope that clears things up.
Set up 2 proportions
562.5 over 12.3 = x over 1
and
353.6 over 8 = x over 1
then cross multiply both of them
12.3x = 562.5
and
8x = 353.6
then divide both of them
round
x = 45.73
and
x = 44.2
