How do you find the discriminant and how many solutions does #-5x^2+7x-2=0# have?
There are 2 solutions, called real roots of the quadratic equations.
Note . We can use shortcut to quickly solve this equation.
Since a + b + c = 0, then one real root is 1 and the other is
When a - b + c = 0, then one real root is (-1) and the other is
