Explanation:
I just learned about quadratic equations in school. The first step of solving quadratic equations is to make sure it is in standard form and equal to 0.
Standard form:
ax^2 + bx + c = 0
It’s P.E.M.D.A.S
P= parenthesis ()
E= exponent
M= multiplication or Multiply
D= Division or divided
A= Addition
S= Subtraction

The equasion has only one solution.

6% = .06
“of” = multiply
so 6% of 9000 can be written as .06 x 9000 , which is 540
