-3y+10=-14 Explain How To Solve The Answer.
2 answers:
To solve 
, isolate variable y
In order to isolate y, move everything from the left side of the equation to the right side of the equal sign. This can be done by performing the opposite math operation than the one listed. The variable will not be transferred over to the other side.
Subtract 10 from the left and right side
Divide -3 from both sides in order to isolate y

<u>Polynomial Remainder Theorem</u>
The polynomial remainder theorem states that the remainder of the division of a polynomial f(x) by (x-a) is equal to f(a).
As a consequence, if a polynomial is divisible by x-a, f(a)=0.
Part 1:
Let's make:
To find out if x+b is a factor of f(x), we find f(-b):
Operating:
The value of f(-b) is not zero. This means Eunju is right, x+b is not a factor of f(x).
Part 2:
We must find out if is a factor of
without using long division or synthetic division.
We can use the polynomial remainder theorem again, but since the factor is not in the form (x-a), we can factor it as follows:
Now we just apply the theorem twice. If both remainders are zero, then the assumption is true.
Let's make:
Find f(-2):
Find f(-3):
Since both f(-2) and f(-3) are zero, is a factor of
