Question

3х(в квадрате) -18=0

Answer 1

$3 {x}^{2} - 18 = 0 \\ 3 {x}^{2} = 18 \\ {x}^{2} = 6 \\ x = ± \sqrt{6}$

Answer 2

To solve the equation 3x^2 - 18 = 0, follow these steps:

Step 1: Add 18 to both sides of the equation to isolate the x^2 term: 3x^2 = 18

Step 2: Divide both sides by 3 to solve for x^2: x^2 = 18 / 3 x^2 = 6

Step 3: Take the square root of both sides to find the value of x: x = ±√6

So, the solutions to the equation are x = √6 and x = -√6.
