Question

9x^2 - 12x + 4 = 0 Solve for x

Answer 1

Answer:

x = 2/3

Step-by-step explanation:

9x2−12x+4=0

Step 1: Factor left side of equation.

(3x−2)(3x−2)=0

Step 2: Set factors equal to 0.

3x−2=0 or 3x−2=0

x=  2 /3

Answer 2

Answer:

Step-by-step explanation:

hello :

9x² - 12x + 4 = 0

a=9   b=-12  c= 4

delta = b²-4ac

delta =  (-12)²- 4(9)(4)=144 - 144 = 0

single solution x = -b/2a = -(-12)/18  = 12/18 = 2/3
