Hi, I am studying quadratics and have a question regrading the solutions for the equation:
4x^2 + 6x +1 = 0 (1)
If I substitute either of the solutions for x into the above, the sum is not 0 ..... how can this be?
X = (-3/4)+SQRT(5)
Or
X = (-3/4)-SQRT(5)
Substituting either of these solutions for x into equation (1)
4x^2 + 6x +1 DOES NOT = 0
so how can it be explained that when y is = 0, these solutions are true?
Thanks in advance for any guidance.
