Question

Rounded to the nearest hundredth, what is the positive solution to the quadratic equation 0 = 2x2 + 3x – 8?

Answer 1

Don't you know the formula?

Answer 2

Looking at the quadratic eq'n that you've shared here, you should see that the coefficients are 2, 3 and -8. Let a=2, b=3 and c =-8.

Substitute these values of a, b and c into the quadratic formula, which is\[x=\frac{ -b \pm \sqrt{b^2-4ac} }{ 2a }\]

Answer 3

If you evaluate this properly, it will give you the two x-values that make the given quadratic equation true.
