Question 437522
Rearrange everything to one side:


*[tex \LARGE 9x^2 - 30x - 25 = 0]


Apply the quadratic formula.


*[tex \LARGE x = \frac{30 \pm sqrt{(-30)^2 - 4(9)(-25)}}{2(9)}]


*[tex \LARGE x = \frac{30 \pm sqrt(1800)}{18} = \frac{30 \pm 30sqrt{2}}{18} = \frac{5 \pm 5sqrt{2}}{3}]


Whew, just learned that I can insert LaTeX code into Algebra.com. LaTeX is quite useful if you eventually publish a paper containing lots of math.
