Question 436618
Solve for x:
Assume the problem is:
{{{(x+1)/x}}} = {{{(-7)/(x+12)}}}
Cross multiply, results
-7x = (x+1)*(x+12)
FOIL
-7x = x^2 + 12x + x + 12
A quadratic equation
x^2 + 13x + 7x + 12 = 0
x^2 + 20x + 12 = 0
Use the quadratic formula to find two solutions
I got: x ~ -19.381;  x ~ -.619
