Should 1.34x10^10 be 1.34(10^10)? Once you reach algebra, you should stop using "x" for multiplication because it will be confused for a variable. Should 0.00267 - x/x^2 be (0.00267 - x)/x^2? Parentheses matter. (0.00267 - x)/x^2 = 1.34(10^10) 0.00267 - x = 1.34(10^10)x^2 0 = 1.34(10^10)x^2 + x - 0.00267 From here, use the quadratic formula.
