Answer:
15
Step-by-step explanation:
substitute the value of the variable into the equation and simply
<em><u>The pair of like terms are:</u></em>

<em><u>Solution:</u></em>
<em><u>Given expression is:</u></em>

We have to find the pairs that are like terms in the given expression
Like terms means that, terms that have same varibale but different ( or same ) coefficients
Here in the given expression "x" and "y" are the two variables present
Arrange the like terms

So here the first two terms has same varibale "y" but different coefficients. So they form a pair of like terms
"x" is present only once . There is no other term with variable "x"
6 and -2 are constants
So the pair of like terms are: 
Answer:
(y - 3)(y - 5)
Step-by-step explanation:
Consider the product of the factors of the constant term which sum to give the coefficient of the y- term
product = + 15, sum = - 8
The factors are - 3 and - 5
y² - 8y + 15 = (y - 3)(y - 5)
