Solve.<br><br> x^2+5x−2=0<br><br> Enter your answers as exact values.
asambeis [7]

The polynomial is not factorable, so we use the quadratic formula.


x^2 + 5x − 2 = 0


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


x = \dfrac{-5 \pm \sqrt{5^2 - 4(1)(-2)}}{2(1)}


x = \dfrac{-5 \pm \sqrt{25 + 8}}{2}


x = \dfrac{-5 \pm \sqrt{33}}{2}


x = \dfrac{-5 + \sqrt{33}}{2}~~or~~x = \dfrac{-5 - \sqrt{33}}{2}


x = -\dfrac{5}{2} + \dfrac{\sqrt{33}}{2}~~or~~x = -\dfrac{5}{2} - \dfrac{\sqrt{33}}{2}

What is 77.5 as a fraction?
butalik [34]
77.5 would convert to 77 1/2. You have 77 whole pieces, and then a half. You could put any fraction for the half part, as long as it is HALF. 
For example, you could also do:
77 5/10
77 6/12
77 2/4
77 10/20
