Question

This is a multiple choice question

y^2=2/3y+2/7

A. The equation has one real solution
B. the equation has two non-real solutions
C. The equation has two real solutions
I believe C is the answer as it can have a + or - answer

Answer 1

get it in standard form: ay^2 + by + c = 0 so you can identify a, b, c.
find (b^2 - 4*a*c) . if it's negative, you have two non-real solns. if it's 0, one real. if it's positive, two real solns.
