Question

(x+6)^2 =(x-4)(x+4)-8

Answer 1

Ответ:

x=5

Пошаговое объяснение:

x^2+12x+36=x^2+4x-4x-16-8

x^2-x^2+12x+36-4x+4x+16+8=0

12x=60

x=60/12

x=5

Answer 3

To solve the equation $(x+6)^2 = (x-4)(x+4) - 8$, you can start by expanding both sides of the equation and then simplifying:

Expanding the left side: $(x+6)^2 = (x+6)(x+6) = x^2 + 12x + 36$

Expanding the right side: $(x-4)(x+4) - 8 = (x^2 - 16) - 8 = x^2 - 24$

Now, you have the equation: $x^2 + 12x + 36 = x^2 - 24$

Next, subtract $x^2$ from both sides of the equation to eliminate the $x^2$ terms:

$12x + 36 = -24$

Now, subtract 36 from both sides to isolate the term with x:

$12x = -60$

Finally, divide both sides by 12 to solve for x:

$x = -60 / 12$ $x = -5$

So, the solution to the equation $(x+6)^2 = (x-4)(x+4) - 8$ is $x = -5$.
