The GCF is 15x.
10X^2
The GCF is 20x.
60x + 120x - 40x - 80x - 30x = 24030x = 240x = 240/3 = 80
It is 10x raised to the second power.
The GCF is 15x^2y^2
362+60x+25 (6x+5)(6x+5)
LCM(5x, 12x) = 60x
(6 - 5x)(6 - 5x)
20x3 - 70x2 + 60x = 10x(2x2 - 7x + 6) = 10x(2x - 3)(x - 2).
The total magnification would be 600x. This is calculated by multiplying the magnification of the eyepiece lens (15x) by the magnification of the objective lens (40x).
if I'm not mistaken... 25x3-60x2+32x right? if that's the case, factor out all commond factors: x(25x2-60x+32) then factor out the trinomial inside: x(5x-4)(5x-8) then that would be the final answer...:D
