Solution for R(n)=(120-6n)(80+8n) equation: 


Simplifying
R(n) = (120 + -6n)(80 + 8n)

Multiply R * n
nR = (120 + -6n)(80 + 8n)

Multiply (120 + -6n) * (80 + 8n)
nR = (120(80 + 8n) + -6n * (80 + 8n))
nR = ((80 * 120 + 8n * 120) + -6n * (80 + 8n))
nR = ((9600 + 960n) + -6n * (80 + 8n))
nR = (9600 + 960n + (80 * -6n + 8n * -6n))
nR = (9600 + 960n + (-480n + -48n2))

Combine like terms: 960n + -480n = 480n
nR = (9600 + 480n + -48n2)

Solving
nR = 9600 + 480n + -48n2

Solving for variable 'n'.

Reorder the terms:
-9600 + -480n + nR + 48n2 = 9600 + 480n + -48n2 + -9600 + -480n + 48n2

Reorder the terms:
-9600 + -480n + nR + 48n2 = 9600 + -9600 + 480n + -480n + -48n2 + 48n2

Combine like terms: 9600 + -9600 = 0
-9600 + -480n + nR + 48n2 = 0 + 480n + -480n + -48n2 + 48n2
-9600 + -480n + nR + 48n2 = 480n + -480n + -48n2 + 48n2

Combine like terms: 480n + -480n = 0
-9600 + -480n + nR + 48n2 = 0 + -48n2 + 48n2
-9600 + -480n + nR + 48n2 = -48n2 + 48n2

Combine like terms: -48n2 + 48n2 = 0
-9600 + -480n + nR + 48n2 = 0
