(2x - 5y)^3 - (2x + 5y)^3

factorize

The answer fam is  -10y • (12x^2 + 25y^2)

Step one: Evaluate, (2x-5y)3   =    8x^3-60x^2y+150xy^2-125y^3

                                  (2x-5y)3   =    8x^3 +60x^2y+150xy^2 +125y^3

Step two: Pull out like factors,  -120x^2y - 250y^3  =   -10y • (12x^2 + 25y^2)

hi,

you half the rectangle that you ae asking about so then you would see the scale factor of 1/2 the one u have selected, the one on top is half.

hope this !
