1. Solve by completing square 2. Use the discriminant to find the number of unique real solutions 3. Solve with quadratic formula
1. t2-5t=7 Discriminant=(-5)2 - 4(1)(7) =25-28 =-3 DiscriminantFind is negative, so there are no real solutions.
Consider the equation 9x2 + 12x - 5=0. (a) Find and state the value of the discriminant, b2 – 4ac. Then state whether one real-number solution, two different real-number solutions, or two...
