You need to group the like terms (the terms with the same or no variable) together so it is:

5y-6y-y +6

Then you combine the like term and it becomes
5y-7y +6
-2y+6
which can also be written as 6-2y

Hope this helps :)

If x+1/x=7,find x^2+1/x^2

trapecia [35]

Answer:

x²+1/x² = 51

Explanation:

Given x - 1/x = 7 ---(1)

We know the algebraic identity:

a²+b²-2ab = (a-b)²

a²+b² = (a-b)²+2ab

Now,

x²+1/x²

= (x-1/x)²+2*x*(1/x)

= (x-1/x)²+2

:7²+2 [ from (1)] =

= 49+2

= 51

Therefore,

x²+1/x² = 51
