Answer:
Your expression equals assuming the problem was to simplify to the form .
Step-by-step explanation:
Let's use the following identity:
which is comparable to the form .
Answer:
t=0 or t=-1/2
Step-by-step explanation:
Solve for t over the real numbers:
t (2 t + 1) = 0
Split into two equations:
t = 0 or 2 t + 1 = 0
Subtract 1 from both sides:
t = 0 or 2 t = -1
Divide both sides by 2:
Answer: |
| t = 0 or t = -1/2
<span>Because you have changed the sign of the divisor as part of setting up the synthetic division.
The whole point of changing the divisor's sign is allow addition (which is easier) instead of subtraction.</span>
Think of it like this:
of = multiplication of the equation
is= equals
and whatever you are looking for is your variable
so....
.40 times X = 56
