<prompt> Tafuta mizizi halisi yafrac x 1x - 35x 2x - 4 fracx 3x - 59x 4 x - 6 - frac2x 5x - 713x 6x - 8 frac92585.Ingiza halisi mizizi, ikitenganishwa na koma.  <response>: Kuzidisha kila nambari na denominator, tunapatafracx2 - 2x - 35x2 - 2x - 8 fracx2 - 2x - 159x2 - 2x - 24 - frac2x2 - 2x - 3513x2 - 2x - 48 frac92585.Tunaweza kuandika haya kamafracx2 - 2x - 8 55x2 - 2x - 8 fracx2 - 2x - 24 99x 2 - 2x - 24 - frac2x2 - 2x - 48 1313x2 - 2x - 48 frac92585. Kwa hivyo,frac15 frac1x2 - 2x - 8 frac19 frac1x2 - 2x - 24 - frac213 - frac2x2 - 2x - 48 frac92585.Hii hurahisishafrac1x2 - 2x - 8 frac1x2 - 2x - 24 - frac2x2 - 2x - 48 0. Hebu y x2 - 2x - 48. Kishafrac1y 40 frac1y 24 - frac2y 0.Kuzidisha kila kitu kwa yy 24y 40, tunapatayy 24 yy 40 - 2y 24y 40 0.Hii hurahisisha hadi 64y 1920 0, hivyo y -30. Kisha x2 - 2x - 48 -30, au x2 - 2x - 18 0. Kwa fomula ya quadratic, x 1 pm sqrt19. Tangu madhehebu sio nzero kwa maadili haya, tunajua kuwa sio ya nje.
