-9,72х²=0

To solve the equation \(-9.72x^2 = 0\), we can follow these steps: 1. **Isolate the variable**: We can divide both sides by -9.72, but since multiplying or dividing by a non-zero constant doesn't change the equality and in this case results in zero: \[ x^2 = 0 \] 2. **Solving for \(x\)**: We take the square root of both sides: \[ x = 0 \] So, the solution to the equation \(-9.72x^2 = 0\) is: \[ x = 0 \]
