To solve the equation \(4x^2 = 100\), we can follow these steps:
-
Divide by 4 to isolate \(x^2\): \[ x^2 = \frac{100}{4} = 25 \]
-
Take the square root of both sides. Remember that taking the square root can yield both a positive and a negative solution: \[ x = \pm \sqrt{25} \] This simplifies to: \[ x = \pm 5 \]
Thus, the complete solution is \(x = 5\) or \(x = -5\), as both values satisfy the original equation \(4x^2 = 100\).
