First get the equation to equal 0 by subtracting 17 from both sides.
You should have x^2+2x-16=0
Next plug your numbers into the quadratic formula(-b^2+/- the square root of b^2-4ac -all divided by 2a)
The end result should be x=-1+/- the square root of 17 or(if you want the decimal) 3.12310562, -5.12310562

melomori [17]
Since the question is using the baby as a reference for much the male and female eats. Treat baby as the variable or x
So 3x+2x+x=181.5lb
6x=181.5lb
x=30.25lb.
female lb.=2×30.25=60.5lb of bamboo
hopefully that helps.

Do this make sense??
Vesnalui [34]
The mistake is that they subtracted 21 instead of adding it. you would have had to added 21 to the left side to cancel it out and added 21 to the right side to get p= 55
