Solve for X
-
Time yourself. I reckon under 30 seconds for most people here: Solve for x: (x+1)(x+2)(x+6) = x^3+9x^2+4(7x-1)

x=2 (3)(4)(8) = 8 + 36 + 52 96 = 96

(x+1)(x+2)(x+6) = x^3+9x^2+20x+12 = x^3+9x^2+4(7x-1) 20x+12=4(7x-1) 5x+3=7x-1 4=2x x = 2
Congratulations! I'm sure you get an A in GSCE maths for that, or possibly even an A at A-level these days. Not that they've dumbed down or anything...

I lost an x somewhere doing it in my befuddled brain.

(x+1)(x+2)(x+6) = x^3+9x^2+4(7x-1) x³ + 9x² + 20x + 12 = x³ + 9x² + 28x - 4 |-x³ 9x² + 20x + 12 = 9x² + 28x -4 |-9x² 20x + 12 = 28x -4 |-20x |+4 16 = 8x x = 2 if not i would say 42 too :-\

You are only half right: x = beer + bacon
