Question

Determine the number of real solutions there are for 9x2 - 12r + 18 = 0.
A. no real solutions
B. I real solution
C. 2 real solutions
D. 3 real solutions
E. not enough information

Answer 1

Answer:

A. No real Solution

Step-by-step explanation:(1): "x2"   was replaced by   "x^2".

(32x2 -  12r) +  18  = 0

9x2 - 12r + 18  =   3 • (3x2 - 4r + 6)

3x2 - 4r + 6

3 • (3x2 - 4r + 6)  = 0

3   =  0
