The Factor Theorem says (x - a) is a factor of function p(x) if p(a)=0
so check for p(-2)
= -2^4 +3(-2)^3 + 4(-2)^2 - 8
= 16 - 24 +16 -8
= 0
so (x + 2) is a factor
Answer:
D = 0; one real root
Step-by-step explanation:
Discriminant Formula:

First, arrange the expression or equation in ax^2+bx+c = 0.

Add both sides by 9.

Compare the coefficients so we can substitute in the formula.

Substitute a = 1, b = 6 and c = 9 in the formula.

Since D = 0, the type of solution is one real root.

Answer:
Net Change in Geno's Field Position = 22 yards
Step-by-step explanation:
Assuming Geno initial position before change is 0
Geno Gained 4 yards three times = 4*3 = 12yards
Geno lose 1 yard twice = 1*(-2) = -2yards
Geno Gained 6 yards twice = 6*2 = 12yards
Net Change in Geno's Field Position = 12 + (-2) + 12 yards
= 22 yards
