Simplify (ab+4a-6)-(ab-6)

$(a b + 4 a - 6) - (a b - 6)$

Step 1

Simplify each term.

Apply the distributive property.

$a b + 4 a - 6 - (a b) - - 6$

Multiply $- 1$ by $- 6$ .

$a b + 4 a - 6 - a b + 6$

Step 2

Combine the opposite terms in $a b + 4 a - 6 - a b + 6$ .

Subtract $a b$ from $a b$ .

$4 a - 6 + 0 + 6$

Add $4 a - 6$ and $0$ .

$4 a - 6 + 6$

Add $- 6$ and $6$ .

$4 a + 0$

Add $4 a$ and $0$ .

$4 a$
