First add 10 to both sides 2x^2-7x-13=-10 2x^2-7x-13+10=-10+10 2x^2-7x-3=0

Now graph 2x^2-7x-3 on graph paper or on a graphing calculator. A graphing calculator is much more accurate so I'd use that.

If you don't have a graphing calculator, you can use something like desmos https://www.desmos.com/calculator
