Answer 1

2х²-72=0

2х²=72

х²=72/2

х²=36

х=+-√36

х1=6

х2=-6

Answer 2

2х в квадрате= 72
Х в квадрате = 36
Х= 6; Х= -6

Answer 3

To solve the quadratic equation 2x^2 - 72 = 0, we need to find the values of x that satisfy this equation. To do that, we can use the quadratic formula:

For a quadratic equation of the form ax^2 + bx + c = 0, the quadratic formula is:

x = (-b ± √(b^2 - 4ac)) / 2a

In our equation, a = 2, b = 0, and c = -72:

x = (-(0) ± √(0^2 - 4 * 2 * -72)) / 2 * 2 x = (±√(0 + 576)) / 4 x = (±√576) / 4 x = (±24) / 4

Now, we get two solutions for x:

1. x = 24 / 4 = 6
2. x = -24 / 4 = -6

So, the solutions to the equation 2x^2 - 72 = 0 are x = 6 and x = -6.
