Question 288564
Which method are you supposed to solve by?

This is a quadratic, so we should set the left side equal to zero:

{{{2x^2 - 5x -3=0}}}

Now you need to factor, or use the quadratic equation.

If you factor, you'll find that:

{{{(2x+1)(x-3)=0}}}


which means that x=-1/2, or x=3.

On a graph, the parabola would cross the x-axis twice.
