x = 601359656/5180645569, answer!

you're going approximately this situation the incorrect way. First set the equation equivalent to 0. 0= -X^2+2x+4 (observe the neg. image in front of the X^2. This equation can't be factored or "dispensed into paretheses" as you call it so for you to use the quadratic formula. the quadratic formula includes 3 variables... A, B, and C. For this equation you have A= -a million, B=2, C=4. Plug in and remedy for X. X= a million+2?5 /-2 simplify and you have your answer! of course no remember what you do you will no longer get a ?6 so C is out... and if A is actual then what got here approximately to the two in the previous the ?5? So A is faulty additionally... that leaves you with... B. very final answer.
