f(t)=(1-6t-3)*(1-6t-3)

Solution for f(t)=(1-6t-3)*(1-6t-3) equation:

Simplifying
f(t) = (1 + -6t + -3)(1 + -6t + -3)

Multiply f * t
ft = (1 + -6t + -3)(1 + -6t + -3)

Reorder the terms:
ft = (1 + -3 + -6t)(1 + -6t + -3)

Combine like terms: 1 + -3 = -2
ft = (-2 + -6t)(1 + -6t + -3)

Reorder the terms:
ft = (-2 + -6t)(1 + -3 + -6t)

Combine like terms: 1 + -3 = -2
ft = (-2 + -6t)(-2 + -6t)

Multiply (-2 + -6t) * (-2 + -6t)
ft = (-2(-2 + -6t) + -6t * (-2 + -6t))
ft = ((-2 * -2 + -6t * -2) + -6t * (-2 + -6t))
ft = ((4 + 12t) + -6t * (-2 + -6t))
ft = (4 + 12t + (-2 * -6t + -6t * -6t))
ft = (4 + 12t + (12t + 36t2))

Combine like terms: 12t + 12t = 24t
ft = (4 + 24t + 36t2)

Solving
ft = 4 + 24t + 36t2

Solving for variable 'f'.

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

Divide each side by 't'.
f = 4t-1 + 24 + 36t

Simplifying
f = 4t-1 + 24 + 36t

Reorder the terms:
f = 24 + 4t-1 + 36t
