### Sample Problem: How to Solve the Quadratic Formula Equation

What are the zeros of $$2x^2+5x-3$$ ?
It means solving $$2x^2+5x-3=0$$ .
The fast way to solve this equation is by factoring which means to rewrite
$$2x^2+5x-3$$ as $$2(x+p)*(x+q)$$
Testing $$p=-3$$ and $$q=.5$$ yields indeed
$$2x^2+5x-3 = 2(x-3)*(x+0.5)$$
implying the two zeros are $$x=3$$ and $$x=-1/2$$.

Using the above Quadratic Formula Calculator to solve $$2x^2+5x-3=0$$ we must enter the coefficients $$a=2, b=5$$ and $$c=-3$$. With steps we see the two zeros are $$x=3$$ and $$x=-1/2$$ .
