Best ResponseYou've already chosen the best response.0In general: ax^2+bx+c=0 In your case: a=1 (the coefficient of x^2) b=3 (coefficient of x) c=8 Use these values and plug them into the discriminant (the thingy inside the square root). \[\Delta=b^24ac\] If the discriminant = 0, there is one real solution If the discriminant > 0, there are two real solutions If the discriminant < 0, there are no real solutions
