x + 6 + 3/x = 0

multiply thru by x

x² + 6x + 3 = 0

Solve for x using the following quadratic formula:
ax² + bx + c = 0
x = (-b ± √(b² - 4ac))/2a

x = (-6 ± √(36 - 12))/2

x = (-6 ± √(24))/2

x = -3 ± √(6)

x ≈ -0.5505, x ≈ -5.449

factor

y^{2b} + 4y^{b} - 12

(y^b + 6)(y^b - 2)

Remember to add exponents when you multiply two numbers, that's why the exponent 2b

I'm missing something, I guess: I thought Yahoo answers was fun and mental exercise - and a chance for people to, perhaps, get a question answered. Are we really keeping score? Best answer?... do I / we care?
