Question Number 26642 by Sr@2004 last updated on 27/Dec/17

9x^2 +41x−204=0. solved it.

$$\mathrm{9}{x}^{\mathrm{2}} +\mathrm{41}{x}−\mathrm{204}=\mathrm{0}.\:{solved}\:{it}. \\ $$

x=((−41±(√(41^2 −4(9)(−204))))/(2(9)))  x=((−41±95)/(18))=3,−7(5/9)

$$\mathrm{x}=\frac{−\mathrm{41}\pm\sqrt{\mathrm{41}^{\mathrm{2}} −\mathrm{4}\left(\mathrm{9}\right)\left(−\mathrm{204}\right)}}{\mathrm{2}\left(\mathrm{9}\right)} \\ $$$$\mathrm{x}=\frac{−\mathrm{41}\pm\mathrm{95}}{\mathrm{18}}=\mathrm{3},−\mathrm{7}\frac{\mathrm{5}}{\mathrm{9}} \\ $$

9×204=1836  9x^2 +68x−27x−204  =x(9x+68)−3(9x+68)  =(9x+68)(x−3)^

$$\mathrm{9}×\mathrm{204}=\mathrm{1836} \\ $$$$\mathrm{9}{x}^{\mathrm{2}} +\mathrm{68}{x}−\mathrm{27}{x}−\mathrm{204} \\ $$$$={x}\left(\mathrm{9}{x}+\mathrm{68}\right)−\mathrm{3}\left(\mathrm{9}{x}+\mathrm{68}\right) \\ $$$$=\left(\mathrm{9}{x}+\mathrm{68}\right)\left({x}−\mathrm{3}\overset{} {\right)} \\ $$
