Problem: using quadratic formula
solve: x + 650x + 105,000 = 2,772,225
IF - and I mean IF - you intended the first
term to be x^2......
-b ± sqrt(b² - 4*a*c)
x = --------------------------
2a
-650 ± sqrt(650² - 4*1*(-2667225))
x = ---------------------------------------------
2(1)
-650 ± sqrt(422500 - (-10668900))
x = ----------------------------------------------
2
-650 ± sqrt(11091400)
x = ------------------------------
2
-650 ± 3330.375
x = -----------------------
2
-650 + 3330.375 -650 - 3330.375
x = ----------------------- and x = -----------------------
2 2
2680.375 -3980.375
x = -------------- and x = ---------------
2 2
x = 1340.1875 and x = -1990.1875
