In this case, the inverse operation to remove the square is the square root. So taking the square root of both sides of the equation x^2 = 25, you get:
x = √25
x = 5 or x = -5
Therefore, the solutions to the equation 4x^2 = 100 are x = 5 and x = -5.
To solve the equation: 4x2=100

25
. You would then use the inverse operation Response area to get x = Response area because both values make the equation true when you substitute in for x in the original equation.
