Question

X^2-0,16=0

Answer 1

• x^2=0,16
• x=0,4 или x= -0,4

Answer 2

To solve the quadratic equation $x^2 - 0.16 = 0$, we can use the quadratic formula:

The quadratic formula states that for an equation in the form $ax^2 + bx + c = 0$, the solutions for $x$ are given by:

$x = \frac{-b \pm \sqrt{b^2 - 4ac}}{2a}$

In our case, $a = 1$, $b = 0$, and $c = -0.16$. Plugging these values into the formula:

$x = \frac{-0 \pm \sqrt{0^2 - 4 \cdot 1 \cdot (-0.16)}}{2 \cdot 1}$

$x = \frac{\pm \sqrt{0.64}}{2}$

$x = \pm \frac{0.8}{2}$

Thus, the two solutions for $x$ are:

$x_1 = \frac{0.8}{2} = 0.4$

$x_2 = -\frac{0.8}{2} = -0.4$

So the solutions to the equation $x^2 - 0.16 = 0$ are $x = 0.4$ and $x = -0.4$.
