solve using the quadratic formula

Answer»

\(\frac{2x}{x-4}+\frac{2x-5}{x-3}=\frac{25}3\)

⇒ 6x(x - 3) + 3(2x - 5) (x - 4) = 25 (x - 3)(x - 4)

⇒ 6x2 - 18x + 6x2 - 39x + 60 = 25x2 - 175x + 300

⇒ 25x2 - 12x2 - 175x + 57x + 240 = 0

⇒ 13x2 - 118x + 240 = 0

⇒ x = \(\frac{118\pm\sqrt{13924-12480}}{26}\)

\(\frac{118\pm\sqrt{1444}}{26}\) \(=\frac{118\pm38}{26}\)

\(\frac{118+38}{26}\) or \(\frac{118-38}{26}\) = 6 or 40/13
