Question

The equation 2x^2 + 15 - 8 = 0 has two solutions. What is the sum of those two solutions?

Answer 1

Answer:

x=(-15±√(79) all over 4

Step-by-step explanation:

You can do this in a few ways but I used the quadratic formula for it. Just plug the numbers into this equation: x= -b ± √(b-4ac) all over 2a.

In this case a=2, b=15, c=-8

Also, there wasn't an "x" behind 15 so I'm doing this by assuming that there is one.
