Question

solve 4x^2+16x+15

Answer 1

as in \[4x ^{2}+16x+15=0?\]

If so, use the quadratic equation. Your equation is in the form \[ax ^{2}+bx+c=0\]
a=4
b=16
c=15

The quadratic equation is
\[x=\frac{-b \pm \sqrt{b ^{2}-4ac}}{2a}\]

Plug in your values for a,b,c for this situation and solve for x. You'll have two answers because of the plus and minus the square root.
