4x^2+5x-4=0 what are the real solutions

will not have real roots that means quadratic equation do not have real solution.

Solution:

Need to determine the real solutions for following quadratic equations

First let’s check whether the given quadratic equation have real roots or not

In our case, equation is

Here a = -4, b = 5 and c = -4

Substituting the values in

So since in our case which is not greater than zero, so quadratic equation will not have real roots that means quadratic equation do not have real solution.

sorry not knowing about that
