The LCM is 40y3
10y2 - 15y2 = -5y2
You need at least two terms to find a GCF.
(5x-9)(2x-1) when factored
(y - 8)(y - 2)
x2 + 10y + 25 doesn't factor neatly. If that was x2 + 10x + 25, it would factor to (x + 5)(x + 5) or (X + 5)2
10x+10y+100 There is a common 10 in each number. 10(x+y+10)
The GCF is 5.
The greatest common factor of 10y plus 15 is 5.
2y-10y
If: x^2+y^2 = 12x-10y-12 Then: x^2+y^2-12x+10y = -12 Completing the squares: (x-6)^2+(y+5)^2 -36-25 = -12 So: (x-6)^2+(y+5)^2 = 49 Therefore the centre of the circle is at (6, -5) and its radius is 7
10x-10y = 0
