Me complete this proof! prove that a quadrilateral is a square. me with the steps for this proof.

After t seconds, a ball tossed in the air from the ground level reaches a height of h feet given by the equation h = 144t-16t^2. after how many seconds will the ball hit the ground before rebounding?

Me find the value of x each figure.
