Question

Which of the following expressions is a common factor when the expressions

Answer 1

Answer:

1 Use this rule: a-b=-(b-a)a−b=−(b−a).

-(16-2)

−(16−2)

2 Use the algorithm method.

1 6

- 2

1 4

3 After simplification, we have:

-(16-2)=-14

−(16−2)=−14

4 Therefore, 2-16=-142−16=−14.

-14

−14

for the second one

1 Collect like terms.

7x+(2+12)

7x+(2+12)

2 Simplify.

7x+14

7x+14
