We can use the ^ symbol to indicate exponents, but in true mathematical format, the equation should look like this:

adding 9 to both sides

simplifying

dividing both sides by 4

simplifying

taking square root of both sides

or simplifying

or further simplifying and final answer

If using the quadratic formula, it would look like this:

converted the original given equation to standard form, notice there is no x term, so we have used as a placeholder

where , , and

and from there, just substitute the numbers in for a, b, and c

or final answer verified
