Question 1183269: A baseball player throws a baseball from a height of 1 m above the ground and its height is given by the equation 𝒉 = −𝟑.2t^𝟐 + 𝟏𝟐.𝟖t + 𝟏, where 𝒉 is the height in metres above the ground, and t, in seconds, is its time in the air [see the image below]. When, to the nearest tenth of a second, will the ball hit the ground? You must solve by factoring

        The request to solve by factoring this quadratic equation

            with non-integer coefficients is   I D I O T I C.


                    It is not factorable (!)


    Also, the quadratic function for the height is written INCORRECTLY.

Hello,  I noticed this style writing  "metres".

I recalled that I solved several problems couple of days ago for a visitor who used  "metres".


I assumed that this visitor has some preliminary knowledge on the subject,  but now I see that this knowledge is zero

not only in these  "flight problems",  but  UNIFORMLY  over all the  Math . . .


Hello,  if it is so,  then   P L E A S E   do not try to create your own problems
and do not litter the  Internet by posting them . . .
