Solve by useng square root \( 4 x^{2}-15=-15 \)

First, let's rearrange the equation. Starting with \( 4x^2 - 15 = -15 \), we can add 15 to both sides to simplify it to \( 4x^2 = 0 \). Then, divide both sides by 4, leading us to \( x^2 = 0 \). Taking the square root of both sides gives us \( x = 0 \). So, the solution to the equation is \( x = 0 \)! And there you have it—solved neatly and with a touch of algebra magic! Keep practicing, and you'll be solving equations in your sleep!
