how do you solve this quadratic equation? tickets= 0.3x^2+12x+10
Please show the work so I can understand.

What do you mean by solve?
If you know x, you can solve for "tickets"
Were you asked to find where tickets is zero?
or
0 = .3 x^2 + 12 x + 10 ????
If that is the case, use the quadratic equation.
