Using quadratic formula:
2(x^2-2x + 1) +4=16
2x^2-4x+6=16
2x^2-4+6-16=0 (then divide both sides by 2)
X^2 -2x- 5= 0
Then use quadratic formula
Answer is;
x = 1 + square root of 6
x = 1 - square root of 6

andreev551 [17]

Answer:

x<−2

Step-by-step explanation:

Let's solve your inequality step-by-step.

6x+12<3x+6

Step 1: Subtract 3x from both sides.

6x+12−3x<3x+6−3x

3x+12<6

Step 2: Subtract 12 from both sides.

3x+12−12<6−12

3x<−6

Step 3: Divide both sides by 3.

3x/3<−6/3

x<−2

Hope this helps :)
