Question

Find the number of real solutions of the quadratic equation with: a = 6, b = 3, c = 2.
A. no real solutions
B. 1 real solution
C. 2 real solutions
D. 3 real solutions

Answer 1

check the value of b^2-4ac if its>0 we have 2 distinct real roots
ifb^2-4ac=0 both roots are real &equal if b^2-4ac<0 we have both roots imaginary

Answer 2

so its A?

Answer 3

b^2 - 4ac
9 - 4(6)(2)
9 - 48 = -39
no solutions since the discriminant is negative.

Answer 4

so it is A? :D thanks again shamil!

Answer 5

yeah.
