I believe the best approach here is the quadratic formula.

solomonzelman · Answer

Here is the quadratic formula:

when the equation is  $\LARGE\color{black}{  \color{blue}{a} x^2+ \color{magenta}{b}x+ \color{red}{c}=0  }$.


(the formula is)

$\normalsize\color{ slate }{\Huge{\bbox[5pt, lightcyan ,border:2px solid  black  ]{  \LARGE{x=~} \huge{  \frac{-\color{magenta}{b} \pm\sqrt{ \color{magenta}{b} ^2-4 \color{blue}{a} \color{red}{c}}}{2 \color{blue}{a}} }~ }}}$

find your a,b,c and plug them in for me please.

If you get a discriminant, you should be already able to tell me how many REAL solutions there are.

anonymous · Answer

There is one real solution is what i got :)

solomonzelman · Answer

What was your discriminant?

solomonzelman · Answer

discriminant is the part inside the square root of the quadratic formula (inside the one I have put in a box)
