How do you simplify y^2 + 11y - 6y + y^2?

$y \left(2 y + 5\right)$

Explanation:

Gather all the similar terms:
${y}^{2} + {y}^{2} = 2 {y}^{2}$
$11 y - 6 y = 5 y$
Therefore, all together it is written as:
$2 {y}^{2} + 5 y$
Now we can factorise:
What factors are in common between $2 {y}^{2}$ and $5 y$?
It's $y$ !
So let's bring that outside the brackets:
$y \left(2 y + 5\right)$
That's it.

You can't derive any value from this as it is an expression and not equal to any number...
