Answer:

5

Step-by-step explanation:

You want me to let you in on a secret? There's a simple equation that you can use to solve any quadratic problem in a minute or two.

It's the quadratic formula

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

The +- means that you will do this two times, the first time you will do -b + sqrt(b^2-4ac), and the second time you will do minus that.

a is the coefficient of the first term in the expression, b is the second and c is the third.

so we getx  = \frac{-(-10) +- \sqrt{(-10)^2  - 4(1)(24)} }{2(1)} , which is the same as

x = \frac{10 + \sqrt{100 - 24(4)} }{2}

and

x = x = \frac{10 - \sqrt{100 - 24(4)} }{2}

The top part simplifies to \frac{10 +  \sqrt{100 - 72} }{2} = \frac{10 + 6}{2}  = 5, which is your answer.
