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.)

10k+5=65
10k=65-5
10k=60
k=60/10
k=6
Answer: k=6

2b-15=33
2b=33+15
2b=48
b=48/2
b=24
Answer: b=24
-----------------------
3d+18=21
3d=21-18
3d=3
d=3/3
d=1
Answer: d=1
Thanks for the extra points i most definitely needed it
The answer is B because <span>(2*15)+(3*15-10)= 65</span>
