Question

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

Answer 1

`y(2y+5)`

Explanation:

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

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