Answer 1

Explanation:

A factor means that it can be multiplied to a number or an expression to form exactly another expression or another number which are not fractions or decimals, they have no remainder. Looking for a factor, you need to see what is being multiplied. The brackets indicates what is being multiplied. Therefore (y + 4) is the factor since it is being multiplied to the number. Even the number

'524 - 3 + 8' is a factor

Further example to familiarize yourself can be

2 x 3 = 6

2 and 3 are both factors of 6. They are both being multiplied to form 6.

Hope this helps.
