sir, in the last question if go ahead on the lines assuming that quadratic has only 1 root, then graph method as well as D=0 wont give ans. Therefore in the question the line should be one of the rootS instead of one of the root. Good question btw.
Good logic but ritwik ek point pe aap thoda galat gaye ho.. maine jo example diya tha graph bana ke usme maine first root ( first root from right side ) ko 0 and 3 ke between liya that why f(3) > 0 but agar main second root ko between 0 and 3 leta toh f(3)
in q2 - question ka pehla line ye keh rha ki A adha time (ghanta) me jitna kam karta he B uska 4\5 th karta he 1 ghante mein right? tu fir us hisab se tu A:B 5:2 huna chaiye na? but apke hisab se ap ye keh rhe hu ki jitna kam A 1 ghante mein karta he uska 4\5th of the work B adha ghanta mein karta he ? does it true ? please check

We can directly use f(3) > 0 in last question. Since there is exactly one root. We should get the same result a^2+ 4a + 3 < 0
