Please no bot answers i really need help im have a 2 percent F in math lol soo A baseball is thrown in the air from center field to home plate. The path of the baseball is represented by the equation p(x)=−7x2+52x+99. How long will it take for the ball to get to home plate?

Tell me what steps went wrong as I solved this problem. Explain how to fix it. Problem:
P(x) = -7x2 +52x+99
Step 1: -7x2 +52x+99 = 0
Step 2: a = -7 b = 52 c = 99Step 3: −52±(52)2−4(−7)(99)√2(−7)
Step 4: −52±5476√14
Step 5:−52±7414
Step 6: x = 117 x = - 9
