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 \(x=-1/2\) .
