-0,1х2+10=0

Let's solve the equation \(-0.1x^2 + 10 = 0\).

1. First, isolate \(x^2\): \[ -0.1x^2 = -10 \] \[ x^2 = \frac{-10}{-0.1} = \frac{10}{0.1} = 100 \]

2. Now, take the square root of both sides: \[ x = \pm \sqrt{100} = \pm 10 \]

So, the solutions for the equation \(-0.1x^2 + 10 = 0\) are: \[ x = 10 \quad \text{and} \quad x = -10 \]
