(t+8)(t+3)=0

Solution for (t+8)(t+3)=0 equation:

Simplifying
(t + 8)(t + 3) = 0

Reorder the terms:
(8 + t)(t + 3) = 0

Reorder the terms:
(8 + t)(3 + t) = 0

Multiply (8 + t) * (3 + t)
(8(3 + t) + t(3 + t)) = 0
((3 * 8 + t * 8) + t(3 + t)) = 0
((24 + 8t) + t(3 + t)) = 0
(24 + 8t + (3 * t + t * t)) = 0
(24 + 8t + (3t + t2)) = 0

Combine like terms: 8t + 3t = 11t
(24 + 11t + t2) = 0

Solving
24 + 11t + t2 = 0

Solving for variable 't'.

0 + t = 0 + -8
t = 0 + -8

Combine like terms: 0 + -8 = -8
t = -8

Simplifying
t = -8
Subproblem 2
Set the factor '(3 + t)' equal to zero and attempt to solve:

Simplifying
3 + t = 0

Solving
3 + t = 0

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

Add '-3' to each side of the equation.
3 + -3 + t = 0 + -3

Combine like terms: 3 + -3 = 0
0 + t = 0 + -3
t = 0 + -3

Combine like terms: 0 + -3 = -3
t = -3

Simplifying
t = -3
Solution
t = {-8, -3}
