Question

Please help me. If you are able to answer any of the following questions please feel free to!

•Describe three ways to solve a quadratic equation.
•How many solutions can a quadratic have?
•List as many synonyms as possible for "solution to an equation"

Answer 1

quadratic is 0=ax²+bx+c

one way is completing the square
that is, get it into a form like k=a(x-h)²

2nd way is factoring
like into form 0=(ax-b)(cx-d)

3rd way is quadratic equation
for 0=ax²+bx+c, $x=\frac{-b+/-\sqrt{b^2-4ac}}{2a}$





2 solutions max because it is 2nd degree



solutions can be called zeroes because that is where y=0
they can also be called roots
