Answer 1

Problem: how many solutions does the problem 9x^2-8x+1=0 have and what is the discrimant
the problem is 9x^2-8x+1=0
I want to know how many solutions and what type of solutions it has
Also I want to know what the discriminant is?

This equation has two real solutions: x = 0.7383 and x = 0.1505.

The discriminant is b² - 4*a*c = -8^2 - 4(9)(1)
64 - 36 = 28
Because the discriminant is positive, the roots are real.
