Question

use the discriminant to find the number and type of solutions: x^2-50x=-625

Answer 1

The discriminant is what is inside the square root in the quadratic formula, b^2 - 4ac
Firs write this as ax^2 + bx + c = 0, then calculate b^2 - 4ac.
Then there are 3 possibilities:
b^2 - 4ac > 0 --> 2 real solutions
b^2 - 4ac = 0 --> 1 real solution
b^2 - 4ac < 0 --> 2 complex solutions
