Answer:
Divide x2 x 2 by 1 1 . Divide 54 54 by 3 3 . Take the square root of both sides of the equation to eliminate the exponent on the left side. The complete solution is the result of both the positive and negative portions of the solution.
x = 3√2
x = -3√2
Step-by-step explanation:
distrbute 3 to right side so
x2 = 54/3
x2 = 18
Then solve:
√x2 = √18
x = √18
x = √9 x 2
x = √ 3 x 3 x 2
x = 3±√2
Extra question:
2x²=12
x² = 12/2
x² = 6
√x² = ±√6
x = + √6
x = - √6
