How many real number solutions does the equation have? 0 = -4x^2 + 7 x - 8

1 answer:

4 0

We have the following expression:
0 = -4x ^ 2 + 7 x - 8
The first thing we must do in this case is to rewrite the expression.
For this, we use the resolver, where:
a = -4
b = 7
c = -8
Getting:
0 = (1/8) * (7 +/- i * root (79))
Answer:
The equation has NO real solutions.
