Question

can somebody tell me how I am to solve this problem?

x+8)(x-19)(x+3)>0
A. The solution set is {x|___}
B. The solution is all real numbers.
C. There is no solution.

Answer 1

well it is zero if:
x = -8
x = 19
x = -3
If x gets really big positive, expression gets big positive
x big negative, expression big negative
sketch that snake
it is greater than zero between -8 and -3 and also when x is greater than 19
and also
