Solve for First Factor:
First, set the first factor equal to zero:
t
+
3
=
0
t + 3 = 0
t
+
3
=
0
. Solving for
t
t
t
gives us
t
=
−
3
t = -3
t
=
−
3
.
Set Second Factor Equal:
Next, set the second factor equal to zero:
t
−
357
=
0
t - 357 = 0
t
−
357
=
0
. Solving for
t
t
t
gives us
t
=
357
t = 357
t
=
357
.
Solve for Second Factor:
Now, we add the two solutions together to find the sum:
(
−
3
)
+
357
=
354
(-3) + 357 = 354
(
−
3
)
+
357
=
354
.
Find Sum of Solutions:
The sum of the solutions to the equation is

, which corresponds to answer choice
