Question

Solve x^2 + x + 7 > 0

Answer 1

Looks like you'll first have to use the quadratic formula (since it won't factor) to find the roots of the equation
x^2 + x + 7 = 0

do you know how to use the quadratic formula?

Then you can use a point test to decide which way the inequalities go.

Answer 2

The quadratic formula gives you undefined points though

Answer 3

Well, that means it doesn't have roots then... that means the x^2 + x + 7 is always positive.

What does that tell you about this x^2 + x + 7 > 0

Are there any x-values you could plug in that will make that statement NOT true?

Answer 4

in other words, can x^2 + x + 7 ever be less than zero?

Answer 5

Thanks dude

Answer 6

Did you find the solution?
