(y+5)(y+1)

y(y+1) + 5(y+1)

=y^2 + y + 5y + 5
= y^2 + 6 y + 5

Thank you damon

To simplify the expression (y+5)(y+1), you can use the distributive property of multiplication over addition.

To do this, multiply each term in the first set of parentheses (y+5) by each term in the second set of parentheses (y+1):

y * y = y^2
y * 1 = y
5 * y = 5y
5 * 1 = 5

Now, combine like terms:

y^2 + y + 5y + 5

Combine y and 5y:

y^2 + (1 + 5)y + 5

Simplify:

y^2 + 6y + 5

Therefore, the simplified expression for (y+5)(y+1) is y^2 + 6y + 5.
