0=-16(t^2-30.25)

Solution for 0=-16(t^2-30.25) equation:

Simplifying
0 = -16(t2 + -30.25)

Reorder the terms:
0 = -16(-30.25 + t2)
0 = (-30.25 * -16 + t2 * -16)
0 = (484 + -16t2)

Solving
0 = 484 + -16t2

Solving for variable 't'.

Move all terms containing t to the left, all other terms to the right.

Add '16t2' to each side of the equation.
0 + 16t2 = 484 + -16t2 + 16t2
Remove the zero:
16t2 = 484 + -16t2 + 16t2

Combine like terms: -16t2 + 16t2 = 0
16t2 = 484 + 0
16t2 = 484

Divide each side by '16'.
t2 = 30.25

Simplifying
t2 = 30.25

Take the square root of each side:
t = {-5.5, 5.5}
