Solution for P(t)=5t^2-20t equation:


Simplifying
P(t) = 5t2 + -20t

Multiply P * t
tP = 5t2 + -20t

Reorder the terms:
tP = -20t + 5t2

Solving
tP = -20t + 5t2

Solving for variable 't'.

Reorder the terms:
20t + tP + -5t2 = -20t + 5t2 + 20t + -5t2

Reorder the terms:
20t + tP + -5t2 = -20t + 20t + 5t2 + -5t2

Combine like terms: -20t + 20t = 0
20t + tP + -5t2 = 0 + 5t2 + -5t2
20t + tP + -5t2 = 5t2 + -5t2

Combine like terms: 5t2 + -5t2 = 0
20t + tP + -5t2 = 0

Factor out the Greatest Common Factor (GCF), 't'.
t(20 + P + -5t) = 0

Subproblem 1

Set the factor 't' equal to zero and attempt to solve: Simplifying t = 0 Solving t = 0 Move all terms containing t to the left, all other terms to the right. Simplifying t = 0

Subproblem 2

Set the factor '(20 + P + -5t)' equal to zero and attempt to solve: Simplifying 20 + P + -5t = 0 Solving 20 + P + -5t = 0 Move all terms containing t to the left, all other terms to the right. Add '-20' to each side of the equation. 20 + P + -20 + -5t = 0 + -20 Reorder the terms: 20 + -20 + P + -5t = 0 + -20 Combine like terms: 20 + -20 = 0 0 + P + -5t = 0 + -20 P + -5t = 0 + -20 Combine like terms: 0 + -20 = -20 P + -5t = -20 Add '-1P' to each side of the equation. P + -1P + -5t = -20 + -1P Combine like terms: P + -1P = 0 0 + -5t = -20 + -1P -5t = -20 + -1P Divide each side by '-5'. t = 4 + 0.2P Simplifying t = 4 + 0.2P

Solution

t = {0, 4 + 0.2P}
