Quadratic Formulas - 10 questions tried 6 times and failed epically. just don't get it. 1) When the sum of 5 and twice a positive number is subtracted from the square of the number, 0 results. Find the number. 2) 2/5x^2 -x+ 19/15 =0 3) .6x^2 = 1.2x +0.6 4) A rule for estimating the number of board feet of lumber that can be cut from a log depends on the diameter of the log. To find the diameter required to get 121 board ft of lumber, the equation (d-4/4)^2 = 121. are both answers reasonable? 5) 9x^2 -7x -5=0 6) 5x^2 - 2x +13 = 18x +1 7) 6p^2 = -19p -3 8) 5x^2 = -20x
