An explosion causes debris to rise vertically with an initial velocity of 64 feet per second. The polynomial 64x - 16x^2 describes the height of the debris above the ground, in feet, after x seconds. Find the height of the debris after 3 seconds. Factor the polynomial. Use the factored form of the polynomial in part (b) to find the height of the debris after 3 seconds. Do you get the same answer as you did in part (a)? If so, does this prove that your factorization is correct? Explain. Show transcribed image text
