Answer: Divide both sides by 2 and apply square root (both sides).
Step-by-step explanation:
Hi, to answer this question we have to analyze the expression given:
2x²=200
A more simple way to solve the expression:
First, we have to divide each side by 2:
2x²/2=200/2
x²=100
Square root on both sides:
√x²=√100
x = -10 and 10
{-10;10}
