Question

(x + 2) (x-2) - x(x-6)=0​

Answer 1

Відповідь:

х=2/3

Пояснення:

х²-4-х²+6х=0

6х-4=0

6х=4

х=2/3

Answer 2

Let's simplify the left-hand side of the equation first:

(x + 2) (x-2) - x(x-6) = (x^2 - 4) - (x^2 - 6x) = x^2 - 4 - x^2 + 6x = 6x - 4

Now we can rewrite the equation as:

6x - 4 = 0

Solving for x, we add 4 to both sides:

6x = 4

Then we divide by 6:

x = 2/3

Therefore, the solution to the equation (x + 2) (x-2) - x(x-6)=0 is x = 2/3.
