a aspect is something that you may flippantly divide a spread by utilising. 6 would nicely be divided by utilising a million, 2, 3, and six. you say she purely needs 3 solutions so as that area seems unusual. a million, 2, and three, are all factors of 6 so those must be astounding. 6 ought to also be a aspect of 6.
Do your own math because if your kids ask you for help then you are never going to know and then they will know that you don't know how to do math!! =( and it is really sad when you have kids and they know that you had to ask for help by other people!!!!

8x^2 - 18
(Factor out GCF, which is 2)
2(x^2 - 9)
(Use difference of two squares to factor x^2 - 9)
2(x - 3)(x + 3)
2
Factor out 2
2(4x^2-9)
What's in parenthesis is the difference of two perfect squares.
2(2x+3)(2x-3)
Math Geek is wrong, you can't factor out an x along with the 2
2(4x^2 - 18)
(2x-3)(2x+3)
the middle terms get cancelled out because of the - and +
