Answer 1

Answer:

x=15

Step-by-step explanation:

2(x-3)²=288

2(x²-6x+9)=288

2x²-12x+18=288

2x²-12x+18-288=0

2x²-12x-270=0

x²-6x-135=0

x²-15x+9x-135=0

(x²-15x)+(9x-135)=0

x(x-15)+9(x-15)=0

(x-15)(x+9)=0

(x-15=0)(x+9=0)

x=15 and x=(-9)

Since the no. cannot be negative

Therefore, x=15.
