300=22t+1.2t^2 multiplying through by 10 to clear the decimal and rearranging, we have
12t2 + 220t -3000 = 0 divide through by 4
3t2 + 55t - 750 = 0 this can't be factored, so let's use the on-site calculator to solve it.....
3×t2+55×t−750=0⇒{t=−(5×√481+55)6t=(5×√481−55)6}⇒{t=−27.4430934995510907t=9.1097601662177573}
And there are the two solutions........
