Best ResponseYou've already chosen the best response.0well i know from there what you do is \[(2t ^{2}87t90)\] then you multiply 90 and 2t squared which gives you 180 then what you have to do is think what times what vies me 180 but also when u add/subtract them it gives you 87 and i dont know those two number

Best ResponseYou've already chosen the best response.0Just use the quadratic equation \[t = [b \pm \sqrt{b^24ac}]/2a\] Where a=2, b=87, c=90. That will give you your two values for t when h=0 allowing you to rewrite the equation as \[h = (tt_1)(tt_2)\]

Best ResponseYou've already chosen the best response.0Then you don't get nice numbers. If it were 88t you'd have: h=(2t+2)(t45) As it is here, you get h=(t + 1.0109863582402774)(t44.510986358240274)
