Solution for 0=t(t+4) equation:


Simplifying
0 = t(t + 4)

Reorder the terms:
0 = t(4 + t)
0 = (4 * t + t * t)
0 = (4t + t2)

Solving
0 = 4t + t2

Solving for variable 't'.
Remove the zero:
-4t + -1t2 = 4t + t2 + -4t + -1t2

Reorder the terms:
-4t + -1t2 = 4t + -4t + t2 + -1t2

Combine like terms: 4t + -4t = 0
-4t + -1t2 = 0 + t2 + -1t2
-4t + -1t2 = t2 + -1t2

Combine like terms: t2 + -1t2 = 0
-4t + -1t2 = 0

Factor out the Greatest Common Factor (GCF), '-1t'.
-1t(4 + t) = 0

Ignore the factor -1.

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 '(4 + t)' equal to zero and attempt to solve: Simplifying 4 + t = 0 Solving 4 + t = 0 Move all terms containing t to the left, all other terms to the right. Add '-4' to each side of the equation. 4 + -4 + t = 0 + -4 Combine like terms: 4 + -4 = 0 0 + t = 0 + -4 t = 0 + -4 Combine like terms: 0 + -4 = -4 t = -4 Simplifying t = -4

Solution

t = {0, -4}
