Calculation:

By distributive property,

$x(8+x)=x\cdot 8+x\cdot x$

$x(8+x)=8x+{x}^{2}$

Replace$x(8+x)\text{}\text{with}\text{}8x+{x}^{2}$

$x}^{2}-6x=8x+{x}^{2$

Add$-{x}^{2}-8x$ on both sides,

${x}^{2}-6x-{x}^{2}-8x=8x+{x}^{2}-{x}^{2}-8x$

Add the like terms,

$0{x}^{2}-14x=0{x}^{2}+0x$

$-14x=0$

$x=0$

The value of x is 0.

Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation:

${x}^{2}-6\cdot x-(x\cdot (8+x))=0$

$(\left({x}^{2}\right)-6x)-x\cdot (x+8)=0$

$-14x=0$

Multiply both sides of the equation by (-1):$14x=0$

Divide both sides of the equation by 14:

$x=0$

Multiply both sides of the equation by (-1):

Divide both sides of the equation by 14:

Use the distributive property to multiply x by 8+x

Subtract 8x from both sides.

-14x=0

Product of two numbers is equal to 0 if at least one of them is 0. Since -14 is not equal to 0, x must be equal to 0.

x=0
