Which among the equation represents for equating the coefficient of x form 3x+2 = (A+B+C) x^2 + (-A + B -2C)x +(-2A), for some A, B, and C. find the value of A.

An object is launched at 15 meters per second from a 50-meter tall platform. The equation for the objects height h at time t seconds after the launch is h(+)=-4.9t^2+15t+50, where h is in meters. Round answers to 2 decimal places. A- how long will it take for the object to reach it's maximum height? B- what will the maximum height of the object be? C- how long will it take the object to hit the ground?
