X^2+2x=2e^7 .............

Original Problem ln(x/2)+ln(x+2)=7

Got through the first few steps, stuck on what to do next at

x^2+2x=2e^7

(just simplify, in terms for x)

x^2+2x=2e^7
Rewrite in standard form:
x^2 + 2x - 2e^7 = 0
Use the quadratic formula:
a = 1
b = 2
c = - 2e^7
x = -1 ± √(1 + 2e^7) ≈ -47.843, 45.843

you cant simplyfy because there are no "like terms"
