Answer:
x=60.56, x=-82.56
Step-by-step explanation:
Solve using quadratic formula
Formula is
[tex]x=\frac{-b+-\sqrt{b^2-4ac}}{2a}[/tex]
0.05x^2 + 1.1x = 250
Subtract 250 on both sides
0.05x^2 + 1.1x - 250=0
a= 0.05, b=1.1 , c=-250
Plug in the values in the formula
[tex]x=\frac{-1.1+-\sqrt{(1.1)^2-4(0.05)(-250)}}{2(0.05)}[/tex]
[tex]x=\frac{-1.1+-7.156116265}{0.1}[/tex]
Now make two equations , one with + and one with -
then we solve for x
[tex]x=\frac{-1.1+7.156116265}{0.1}[/tex]
x=60.56
[tex]x=\frac{-1.1-7.156116265}{0.1}[/tex]
x=-82.56
