Consider the equation 1+n+6/n+1=4/n-2

A. What is the LCD of the rational expressions

B. What values must be excluded from the list of possible solutions

C. What is the solution of the equation?

For part C I got n = negative 1 plus or minus the square root of 145, everything divided 4.

Step-by-step explanation:

My part A and B were the same as the persons above answer.

x = ±sqrt(10)

step-by-step explanation:

5 - 2x² = -15

subtract 5 from each side

5-5 - 2x² = -15-5

-2x^2   = -20

divide by -2 on each side

-2x^2   /-2= -20/-2

x^2 =10

take the square root on each side

sqrt(x^2 )=±sqrt(10)

x = ±sqrt(10)

check:

5 - 2x² = -15

+sqrt(10)

5 - 2(sqrt(10))² = -15

5 -2(10) = -15

5 -20 = -15

-15 = -15

-sqrt(10)

5 - 2(-sqrt(10))² = -15

5 -2(10) = -15

5 -20 = -15

-15 = -15
