Answer:
Step-by-step explanation:
For a quadtratic in the form of
[tex]ax^{2} + bx + c = 0[/tex]
The solutions to this can be found using the quadratic formula:
[tex]x = \frac{-b \pm \sqrt{b^{2} - 4ac}}{2a}[/tex]
For the given equation, [tex]a = 1[/tex], [tex]b = 2[/tex], [tex]c = -15[/tex]. Plugging these numbers into the formula will give you the answer.
