1 Factor completely.
p2+7p+10 = (p + 5)(p + 2)
2 Factor completely.
x2+10x+16 = (x + 4)(x + 6)
3 Factor completely.
x2+7x−18 = (x + 9)(x - 2)
4 Factor completely.
x2−5x−24 = (x - 8)(x + 3)
5 Factor completely.
x2−3x−40 = (x - 8)(x + 5)
I percieve this as a trick question. The probability is 100% because if the 3 randomly selected students pertain to the group of students who like statistics better than algebra, then obviously, they are all going to say they like stats better than algerbra.
I believe the answer is 8 2/6 witch would rescue to 8 1/3 . Ok I'm not 100% positive but that look about right. Sorry if it is wrong.
Just grab your calculator and multiply it by itself or use the 'square' function
Answer is 4040.233866
X=0 (4×0)+3=3 that I think is the absolute value
