The LCM of these numbers is 25y. LCM is Least Common Multiple.
LCM(5y3, 25y6) = 25y6
The LCM of 8x and 25y is 200xy
5y + 7 = 25y = -5y = -1
(5y - 2)(5y + 2)
(5y - 6)(5y + 6)
Their product.
The LCM is 30xy.
It is 5*(2x - 5y).
25y**8/15y**5 25y**3/15 5y**3/3 (5/3)y**3
I think that wants to be 16x2 - 40xy + 25y2 That factors to (4x - 5y)(4x - 5y) or (4x - 5y)2
(8x + 5y)(64x^2 - 40xy + 25y^2)
Well, the way you wrote it, you would have:(4x - 5y - 3) x 3x + 5ywhich would give12x^2 - 15xy - 9x + 5yBut, if you meant the quantity (3x + 5y), then you would have:(4x - 5y - 3) x (3x + 5y)which would give12x^2 - 15xy - 9x + 20xy - 25y^2 - 15yand combining terms12x^2 - 25y^2 + 5xy - 9x - 15y
