3x2 - 18x + 225 = 6

What's the answer

12.5

Step-by-step explanation:

1) Original equation: 3 (2) - 18x + 225 = 6

2) Simplify: 6 - 18x + 225 = 6

3) Move 18x over to the right: 6 + 225 = 6 + 18x

4) Move the 6 on the right over to the left: 225 = 18x

5) Divide both sides by 18 to isolate x: 225/18, 18x/18

6) x = 12.5
