Answer:
f(x) = (x + 11) (x + 3) (x − 1) (x − 3)
Step-by-step explanation:
f(x) = x⁴ + 10x³ − 20x² − 90x + 99
f(x) is a fourth order polynomial, so it has 4 roots. Use rational root theorem to find possible rational roots.
±99, ±11, ±9, ±3, ±1
By trial and error, the zeros are -11, -3, 1, and 3.
f(x) = (x + 11) (x + 3) (x − 1) (x − 3)
Hey, the numbers could be a=14 and b=9:
a+b=14+9=23 and a - b = 14 - 9 = 5 :)
Well, if earth's climate is getting warmer then the glaciers would probably start to melt. I'm not sure how to answer the second one either, maybe since glaciers are so big, they would be a lot of animals living on them and they would loose their habitat maybe causing them to have to move somewhere else?
