When
the ball is in the ground, its height is basically equal to zero thus making
our equation,
<span> -16t^2 + 272t + 1344 = 0</span>
Simplifying
the equation will give us,
<span> - t^2 + 17t + 84 = 0 or t^2 – 17t – 84 = 0</span>
Factoring
out the equation will give us,
<span> (t – 21)(t + 4) = 0</span>
Thus,
t = 21 or t = -4. -4 is an extraneous root. Thus, the answer is t = 21.
<span>Answer:
21 seconds</span>
hello :
<span> (21)(7)(3x) = (21×7×3)(x) = 441x </span>
In order to factor a polynomial, you have to find its roots
So that you can factor it as
So, in this case, we're looking for the solutions of
So, the polynomial can be written as
