how many real number solutions does the equation 7x^2 -5x + 1= 0

Question

how many real number solutions does the equation 7x^2 -5x + 1= 0. I struggle in algebra 2 and need lots of help.

Answer 1

The discriminant of the quadratic formula, b² - 4ac, indicates the number of real roots.

If b2 - 4ac > 0, the function has two real roots.

 

(-5)² - (4)(7)(1)

25 - 28

-3

 

The function does not have any real roots.
