Question

Use the quadratic formula to find the roots of the equation. Round to tenths if necessary. x2 + x +10 = 0
	A.	{3.2}
	B.	{-5.5, -2}
	C.	{-3.2, 3.2}
	D.	no real number solution

hero · Answer

$$x = \frac{-b \pm \sqrt{b^2-4ac}}{2a}$$

hero · Answer

But actually, just do b^2 - 4ac to make sure that it is even necessary to do quad form

hero · Answer

(1)^2 - 4(1)(10) = 1 - 40 = -39
 
Since discriminant is negative, this means that there are no real solutions
