Alejandro Horton · Answer 1

For the equation:

-1=5 x^2 - 2 x

5 x^2 - 2 x + 1 = 0, then we substitute: a=5, b=-2, c = 1

to discriminant formula: D = b^2 - 4 a c = (-2) ^2 - 4 * 5 * 1 = 4 - 20 = - 16

Answer:

The discriminant is equal to - 16 which means the equation has no real number solutions.
