Any negative or positive number inside an absolute value will always come out positive.
Lisa is measuring the depth of a well. She drops a ball from a height of h feet into the well and measures how long it takes the ball to hit the bottom of the well.
Polynomial = 
where 0 is the initial speed and h is height it was dropped .
Now find depth of the well, when t = 3.5 seconds and h = 6 ft
= 
= 
= -196 + 6
= -190
So depth of the well is 190 feet (negative sign represents the depth, below the ground)

Jimmy - j years now
Beth -(j+2) years now
In 3 years
Jimmy - (j+3)
Beth -(j+2+3)=(j+5)
j+3 + j+5=(2j+8) - sum of their ages in 3 years
y years ago
Jimmy - (j-3)
Beth - (j+2-3)= (j-1)
j-3+j-1=(2j - 4) - sum of their ages in 3 years ago
(2j+8) =2(2j - 4)
2j+8 = 4j-8
2j = 16
j = 8
Jimmy - 8 years now
Beth - 8+2=10 years now
