0=t(-4.9t+25t)

Solution for 0=t(-4.9t+25t) equation:

Simplifying
0 = t(-4.9t + 25t)

Combine like terms: -4.9t + 25t = 20.1t
0 = t(20.1t)

Remove parenthesis around (20.1t)
0 = t * 20.1t

Reorder the terms for easier multiplication:
0 = 20.1t * t

Multiply t * t
0 = 20.1t2

Solving
0 = 20.1t2

Solving for variable 't'.

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

Add '-20.1t2' to each side of the equation.
0 + -20.1t2 = 20.1t2 + -20.1t2
Remove the zero:
-20.1t2 = 20.1t2 + -20.1t2

Combine like terms: 20.1t2 + -20.1t2 = 0.0
-20.1t2 = 0.0

Divide each side by '-20.1'.
t2 = 0

Simplifying
t2 = 0

Take the square root of each side:
t = {0}
