How do I factor 4x^2-12x+8?
so far I took out the Greatest Common Factor.
do you know how to use the diamond? or were you taught with the FOIL square?
Never heard of diamond. I've heard of FOIL.
Then you would use FOIL, and find which two numbers multiply to get 2, and add to get -3
Ok that's what I thought. I tried to do that.
-2 x 1=-2
-2 + 1=-1
2 x 1=3
-1 x 2=-2
I don't know what other numbers multiply to 2.
Try making both 2 and 1 negative
oh wow haha.
how do you work the following question out:
if you have a rectangle, whos length is five cm longer than twice it width and has an area of 207com what are the values off the length and width
any help of any kind would be welcome.
