1.6 6x4=24
x4
____
6. 4
2
don't know if u get it but here u go
Since its x + 3 we use -3
-3| 2 1 -8 21 (these are the # without the x)
___________________
-6 15 -21
-------------------------------
2 -5 7 0
Drag the 2 down, multiple it by -3 to get -6
1+(-6) = -5. -5 * -3 =15 . 15+(-8) = 7
7*-3 = -21. -21 +21 = 0
Since last # is 0 we have a factor.
factor is 2x^2 -5x -7 (we start with a power 1 less the original.)
