Solution for 0=t(7t+2) equation:


Simplifying
0 = t(7t + 2)

Reorder the terms:
0 = t(2 + 7t)
0 = (2 * t + 7t * t)
0 = (2t + 7t2)

Solving
0 = 2t + 7t2

Solving for variable 't'.
Remove the zero:
-2t + -7t2 = 2t + 7t2 + -2t + -7t2

Reorder the terms:
-2t + -7t2 = 2t + -2t + 7t2 + -7t2

Combine like terms: 2t + -2t = 0
-2t + -7t2 = 0 + 7t2 + -7t2
-2t + -7t2 = 7t2 + -7t2

Combine like terms: 7t2 + -7t2 = 0
-2t + -7t2 = 0

Factor out the Greatest Common Factor (GCF), '-1t'.
-1t(2 + 7t) = 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 '(2 + 7t)' equal to zero and attempt to solve: Simplifying 2 + 7t = 0 Solving 2 + 7t = 0 Move all terms containing t to the left, all other terms to the right. Add '-2' to each side of the equation. 2 + -2 + 7t = 0 + -2 Combine like terms: 2 + -2 = 0 0 + 7t = 0 + -2 7t = 0 + -2 Combine like terms: 0 + -2 = -2 7t = -2 Divide each side by '7'. t = -0.2857142857 Simplifying t = -0.2857142857

Solution

t = {0, -0.2857142857}
