Answer 2

Answer:

x=15 or x=-9

Step-by-step explanation:

2(x−3)2=288

Step 1: Simplify both sides of the equation.

2x2−12x+18=288

Step 2: Subtract 288 from both sides.

2x2−12x+18−288=288−288

2x2−12x−270=0

For this equation: a=2, b=-12, c=-270

2x2+−12x+−270=0

Step 3: Use quadratic formula with a=2, b=-12, c=-270.

x= −b±√b2−4ac /2a

x= −(−12)±√(−12)2−4(2)(−270) /2(2)

x= 12±√2304 /4

x=15 or x=−9
