Answer:
first, subtract 17 on both sides: x²+2x-16=0
this cannot be factored, so use the quadratic formula to solve for x:
b²-4ac=2²-4(10(-16)=4+64=68
√68=2√17
so x=(-2+2√17)/2 or x=(-2-2√17)/2
x=-1+√17 or x=-1-√17

Answer: The probability of rolling a number greater than two is 5/6.
Step-by-step explanation:
So there are 12 possible outcomes for rolling a number greater than two since the die is numbered from 1 to 12.
And in all the numbers, 10 of which is greater than 2.
so you will divide 10 over the total outcomes.
10/12 = 5/6 or 0.833..
