2(3x - 1)(3x + 1)
62.
41 + 15 = 36 4 x 9
There is more than one way, but the idea of a factor tree is an easy way to do it. Start with 36 itself. A number is always a factor of itself since 36x1=36. Now since you know 36 is even, divide it by 2 and you have 18. See how it did it below and continue dividing. 36=18x2=9x2x2=3x3x2x2=3x3x2x2x1 So looking at the above we have The first thing after the 36 is 18 and 2 so those are two factors. I will use[ ] for my factor list. [Factor list]=[18,2] Next we have 9x2x2 so 9 and 9x2 are factors. [ 18,2,9] Now we have 3 ( we have 9 too, but I already have it) and we have 3x2=6 and 2x2x3=12 [18,2,9,3,6 12] Now we have 1 also [1,2,3,6,9,12,18,36]
18x2 + 15x + 2 = (3x + 2)(6x + 1)
3x3-18x2+24x=3x(x2-6x+8)=3x(x-4)(x-2)
That's a factor string of 36.
2(3x + 1)(3x - 1)
2(3x - 1)(3x + 1)
18x2
6x6, 9x4, 4x9, 3x12, 12x3, 2x18, 18x2
No but it goes into 36 evenly. 18x2=36 not 32
3x(x - 2)(x - 4)
2 cups = 1 pint multiply 18x2 = 36 cups.
(x + 2)(3x - 1)(3x + 1)
6x3=18 and 18x2=36 so Thirty-Six
