# Math Help - quadratic formula

solve
$\frac{x(15x-1)}{2}=1$

2. $\displaystyle \frac{15x^2}{2}-\frac{x}{2}-1=0$ Now factor or apply the formula whichever works.

3. Continuing where dwsmith left off, and multiplying both sides by 2:

$15x^2-x-2=0$

Factor:

$(5x-2)(3x+1)=0$

Now, by the Zero-product property:

$5x-2=0$ and $3x+1=0$

solving gives us:

$x=\frac{2}{5}$

$x=-\frac{1}{3}$
