8-2 and then 3 divided by 6 which will give you 0.5 so x=0.5
X^2 +2x +10 = 0
D = 4 -40 = - 36
x_1,2 = (-2 +/- sqrt(-36))/2 = (-2 +/- 6i)/2 = 2(-1 +/- 3i)/2 = -1 +/- 3i
x_1,2 = -1 +/- 3i or more understandably
x_1 = -1 -3i and x_2 = -1 +3i
hope this will help you
Three consecutive numbers can be written as x, x+1, and x+2, but they also can be written x, x-1, and x-2 where x is the biggest number.
sum means adding... so

combine like terms and solve for x!
Answer:
Step-by-step explanation:
x²-px-p-c=0
sum of roots=α+β=-b/a=p
product of roots=αβ=c/a=-p-c
(α+1)(β+1)=αβ+α+β+1=-p-c+p+1=-c+1
The GCF of 4 and 7 is 1
The factors of 4 are 1, 2, and 4
The factors of 7 are 1 and 7
1 is the greatest number that they have in common so 1 is the GCF.
