Answer:
The product of the other two zeros is c
Step-by-step explanation:
Let α, β and γ be the zeros of the polynomial x³ + ax² + bx + c. Since one of the zeros is -1, therefore let γ = -1. Hence:
sum of the roots = α + β + γ = -a
-1 + β + γ = -a
β + γ = -a + 1
αβ + αγ + βγ = b
-1(β) + (-1)γ + βγ = b
-β -γ + βγ = b
Also, the product of the zeros is equal to -c, hence:
αβγ = -c
-1(βγ) = -c
βγ = c
Hence the product of the other two zeros is c

Answer:
3N + 4
Step-by-step explanation:
The number next to the parenthesis means that you multiply everything inside the parentheses by that number.
1/2(6N+8) = 3N+4
X-4/2 = 10
x+-2=10
x-2=10
x-2+2=10+2
x=12
