Given :
re - writing the equation , we have
we need to find the value of a and b for which -2<x < 4 , this means that the roots of the quadratic equation are -2<x < 4.
The formula for finding the quadratic equation when the roots are known is :
- sum of roots(x) + product of root = 0
sum of roots = -2 + 4 = 2
product of roots = -2 x 4 = -8
substituting into the formula , we have:
, which could be written in inequality form as
comparing with , it means that :
Terry needs 22 feet of material. One yard is three feet, and he needs 4 yard-long scarves, so multiply 3 by 4, which gives you twelve. Next, figure for the hats. He needs 30 inches for 4 hats each, so multiply 30 by 4. That'll give you 120 inches. Convert the 120 inches to feet and you've got 22 feet total!
