There is a 1 in 10/3 chance that 7 is selected. Picking more digits makes the probability of it being picked higher.
X^2+10x+21/x+3? If you meant (<span>x^2+10x+21)/(x+3), please note that those parentheses are essential.
If you wish to divide </span><span>x^2+10x+21 by (x+3) using synth. div., use the divisor -3:
_______________
-3 / 1 10 21
-3 -21
-----------------------
1 7 0
Since the remainder is 0, (x+3) is a divisor of </span><span>x^2+10x+21, and the other factor is (1x + 7).</span><span>
