How to find the greatest common factor of 42, 98, 140

2) How to find the greatest common factor for. 36b(small 3), 45b(small 3), 54b(small 3)

3) Factor. 70x(small 3) - 56x(small 2)

4) Factor by grouping. x(small 3) - 5x(small 2) + 2x - 10


Thank you.

Hi

I am guessing that "small 3" means cubed.

2)

36*b^3=2*2*3*3*b*b*b

45*b^3=3*3*5*b*b*b

54*b^3=2*3*3*3*b*b*b

So we need two 2's ,three 3's,one 5's and 3 b's so

GreatestCommonFactor(36b^3,45b^3,54b^3…

3)

70x^3=2*5*7*x*x*x

56x^2=2*2*2*7*x*x

70x^3-56x^2=2*5*7*x*x*x-2*2*2*7*x*x=2*… * (5x-4)

4)

x^3 - 5x^2 + 2x - 10=x*x*x-5*x*x +2*x-2*5=x*x*(x-5)+2*(x-5)=(x*x+2)*(x-5)…

1) 42, 98, 140 = 14
2) Small three? You mean "exponent?"
3) Wait . . . can't you just google it?
4) USE GOOGLE, IT'S FASTER THAN THIS!!!
