Step-by-step explanation:
Answer:
9/2
distribute the value of x,y, and z, on the given questions, and then you do multiplication, next addition, lastly lowest term.
The slope is -2. You find this by putting the rise between the two points over the run.
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.)
