(6x-5y)^2=
36x-25y
6x-5y

(4x+5y)^2
16x+25y
4x+5y

Please check to see if right. If not corrected for me.

• math -

You need to expand both of these.
(6x-5y)^2=
(6x-5y)(6x-5y)
36x^2-60xy+25y^2

Now try doing the second one this way. Post if you want it checked.

• math -

(4x+5y)^2
(4x-5y)(4x+5y)
16x^2-40xy+25y^2
