Answers
Answer
are you sure?
Answer
the discriminant is (1)² - 4(-3)(-4)) = 1 - 48 = -47
since it is negative there are 0 real roots
since it is negative there are 0 real roots

I apologize for the error in my previous response. Let's solve the equation to find the number of real number solutions.
The equation is 0 = -3x² + x - 4.
We can use the quadratic formula to find the solutions:
x = (-b ± √(b² - 4ac)) / 2a
In this case, a = -3, b = 1, and c = -4.
Plugging in these values:
x = (-(1) ± √((1)² - 4(-3)(-4))) / 2(-3)
x = (-1 ± √(1 + 48)) / -6
x = (-1 ± √49) / -6
x = (-1 ± 7) / -6
So, the solutions for x are:
x = (6 / -6) = -1
x = (-8 / -6) = 4/3
Therefore, there are indeed 2 real number solutions to the equation 0 = -3x² + x - 4. Thank you for pointing out the mistake.
