Solve for the variable write your answers as integers or as proper or improper fractions in simplest form 3x^2-75=0
To solve the equation 3x^2 - 75 = 0:
Add 75 to both sides:
3x^2 = 75
Divide by 3 on both sides:
x^2 = 25
Take the square root of both sides:
x = ±5
Therefore, the solutions for the variable x are x = 5 and x = -5.
