LCM(12x, 40y3) = 120xy3

That will depend on the value of x

2*2 - 12x +16 =0 4 - 12x +16 =0 -12x + 16 +4 =0 -12x + 20 =0 -12x = -20 x = 1.666666667

The Least Common Multiple is 120xy.

(-6x)(-12x)(-4) = -(6x)(12x)(4) = -[(6)(12)(4)][(x)(x)] = -(288)(x^2) = -288x^2

12x - 4 = 7x - 21 12x -7x = -21 + 4 5x = -17 x = -3.4

The GCF is 4.

12x - 8 = 10x + 42x = 12x = 6

There's a chance this was notated incorrectly. It looks like it wants to be some combination of 3x and 2. 9x2 + 12x + 4 = (3x + 2)(3x + 2) or (3x + 2)2 -9x2 - 12x - 4 = -(3x + 2)2 9x2 - 12x + 4 = (3x - 2)2 -9x2 + 12x - 4 = -(3x - 2)2

3x * (x - 4) = 3x*x - 3x*4 = 3x^2 - 12x.

The LCM is 4.

(6x^5 + 12x) / (-2x^-3) =[ (6x^5 + 12x) (x^3) ] / (-2) =(6x^8 + 12x^4) / (-2)=(3x^8 + 6x^4) =(3x^4)[ (x^4) + 2 ]

Since the second one is a multiple of the first, it is automatically the LCM.
