Answer:
y = 2(x-3)^2 - 2
Step-by-step explanation:
y = 2x^2 - 12x + 16
y = 2(x^2 - 6x + 8)
y = 2(x^2 - 6x +8 +1 -1) you "complete the square" by bringing the last term (8) up to "half of the middle co-efficient squared". Middle co-efficient is -6, half is -3, squared is 9. To get from 8 to 9 you must add 1 (+1), but if you add 1 you must subtract 1 (-1) so that you don't change the overall value of inside the bracket
y = 2(x^2 - 6x +9) - 2 (bring the -1 outside of the brackets)
y = 2(x-3)^2 - 2

Step-by-step explanation:
The least common multiple of 3 and 4 is 12. Divide the rectangle in twelfths.
⅓ = 4/12
¼ = 3/12
Answer:
x = 7 x = -1
Step-by-step explanation:
3|x − 3| + 2 = 14
Subtract 2 from each side
3|x − 3| + 2 -2= 14-2
3|x − 3| = 12
Divide by 3
3|x − 3| /3 = 12/3
|x − 3| = 4
Now the absolute value has a positive and negative solution.
x-3 = 4 x-3 = -4
Add 3 to each side
x-3+3 = 4+3 x-3+3 = -4+3
x = 7 x = -1
