1296=-16(t-9)(t+9)

Solution for 1296=-16(t-9)(t+9) equation:

Simplifying
1296 = -16(t + -9)(t + 9)

Reorder the terms:
1296 = -16(-9 + t)(t + 9)

Reorder the terms:
1296 = -16(-9 + t)(9 + t)

Multiply (-9 + t) * (9 + t)
1296 = -16(-9(9 + t) + t(9 + t))
1296 = -16((9 * -9 + t * -9) + t(9 + t))
1296 = -16((-81 + -9t) + t(9 + t))
1296 = -16(-81 + -9t + (9 * t + t * t))
1296 = -16(-81 + -9t + (9t + t2))

Combine like terms: -9t + 9t = 0
1296 = -16(-81 + 0 + t2)
1296 = -16(-81 + t2)
1296 = (-81 * -16 + t2 * -16)
1296 = (1296 + -16t2)

Add '-1296' to each side of the equation.
1296 + -1296 = 1296 + -1296 + -16t2

Combine like terms: 1296 + -1296 = 0
0 = 1296 + -1296 + -16t2

Combine like terms: 1296 + -1296 = 0
0 = 0 + -16t2
0 = -16t2

Solving
0 = -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 = -16t2 + 16t2
Remove the zero:
16t2 = -16t2 + 16t2

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

Divide each side by '16'.
t2 = 0

Simplifying
t2 = 0

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