Simplify (x^2-x-6)-(x^2-x-6)

$(x^{2} - x - 6) - (x^{2} - x - 6)$

Step 1

Simplify each term.

Apply the distributive property.

$x^{2} - x - 6 - x^{2} - - x - - 6$

Simplify.

Multiply $- - x$ .

Multiply $- 1$ by $- 1$ .

$x^{2} - x - 6 - x^{2} + 1 x - - 6$

Multiply $x$ by $1$ .

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

Multiply $- 1$ by $- 6$ .

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

Step 2

Combine the opposite terms in $x^{2} - x - 6 - x^{2} + x + 6$ .

Subtract $x^{2}$ from $x^{2}$ .

$- x - 6 + 0 + x + 6$

Add $- x - 6$ and $0$ .

$- x - 6 + x + 6$

Add $- x$ and $x$ .

$0 - 6 + 6$

Subtract $6$ from $0$ .

$- 6 + 6$

Add $- 6$ and $6$ .

$0$
