Step-by-step explanation:

List all the factors for 15 ( 1and 15) (3 and 5) use a number thats is bigger than Leila's but not bigger than Jo's the only one is 3, multiply 2 and 3, and 3 and 3 your numbers should be 6 (2x3) and 9 (3x3) add them together to make 15 then you got it.

we are given polynomial 2x^2 +4x +7.

we need to determine the number of roots of the given polynomial using the fundamental theorem of algebra.

a) for the given polynomial 2x^2+4x+7, we have degree =2.

b) let us find the roots of the given polynomial.

2x^2+4x+7= 0
