Find the number of real number solutions for the equation. x^2+5x+7=0

koban [17]

Given a quadratic equation $ax^2+bx+c=0$ , we define the discriminant as

$\Delta = b^2-4ac$

The number of real solutions of the equation depend on the sign of $\Delta$ :

If $\Delta>0$ the equation has two solutions
If $\Delta=0$ the equation has one double solution
If $\Delta$ the equation has no real solutions

In this case, we have

$\Delta = 25-28=-3$

And so this equation has no real solutions.
