If there is no number in between sets of numbers, it's going to be multiplication.
So (w+2) x (w+7)
w+2, well, evaluates into w+2.
w+7 is w+7.
We'll use the FOIL method for this.
FOIL stands for:
First
Outer
Inner
Last
Let's start with the first terms. Multiply them.
So: w * w.
Combine both w's, and you get
.
Now multiply the outer terms.
w * 7 = 7w.
Then the inner terms. 2 and w.
2 x w = 2w.
So our current numbers are:, 7w, and 2w.
We can add 7w and 2w together.
7w + 2w = 9w.
Now multiply the last terms.
2 x 7 = 14.
So, this simplifies to

Answer:
The polynomial function
To determine the multiplicity of 0, -2, -4, 5.
The multiplicity of a root is the number of times the root appears.
First find the root of the equation, set the function equals to zero.
therefore, the root of this function are, x=0,-2, -4, 5
To find the multiplicity of the roots:
A factor of x would have a root at x=0 with multiplicity of 1
similarly, x=-2 with multiplicity of 3
x=-4 with multiplicity of 2
x=5 with multiplicity of 4.
