(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.

    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

    check this for me please
