In the expression 2x, the 2 is the coefficient. It tells you how many of the x you need.
In the beginning, no you need not cull the special coefficient
To find the coefficient of the variable term, we need to combine like terms. The coefficient of the variable term -1.5r is -1.5. The coefficient of the variable term 6r is 6. The coefficient of the variable term -12.2r is -12.2. Thus, when combined, the coefficient of the variable term is -1.5 + 6 - 12.2, which simplifies to -7.7.

First, put the number that the variable is equal to on the left, then put the leading coefficient inside and every coefficient after that on the left. If there's a term missing, for example this is missing an x2, put a zero in the spot it would be in. Then, take the leading coefficient down to the bottom. [Then multiply it by the number on the left and place it under the place where the next coefficient is. Then add those numbers and put the sum below them.] Repeat the steps that are surrounded by brackets until you get the answer, which is the number that is on the lower right. Example: For 4x4+6x3-3x-4 when x=2 2|4 6 0 -3 -4 Bring 4 down. Multiply by 2 to get 8. Add 6 to get 14. Multiply by 2 to get 28. Add 0 to get 28. Multiply by 2 to get 56. Add -3 to get 53. Multiply by 2 to get 106. Add -4 to get 102. 102 is the answer.
Coefficient
In the expression 2x, the 2 is the coefficient. It tells you how many of the x you need.
The binomial usually has an x2 term and an x term, so we complete the square by adding a constant term. If the coefficient of x2 is not 1, we divide the binomial by that coefficient first (we can multiply the trinomial by it later). Then we divide the coefficient of x by 2 and square that. That is the constant that we need to add to get the perfect square trinomial. Then just multiply that trinomial by the original coefficient of x2.
In the beginning, no you need not cull the special coefficient
You can do this by finding two numbers that add to make 18 (the coefficient of the middle term) and multiply to make 65 (the product of the first term's coefficient and the last term). As it happens, 65 only has two factors, 5 and 13, which do add up to make 18. Unfortunately, they won't work for this equation, as we need them to add up to 18, and multiply to make negative 65. So this statement can not be factored.
If both the frictional force and coefficient of friction are variable and not given, it is not possible to calculate the friction force using the equation friction = coefficient of friction x normal force. The relationship between these variables would need to be explicitly provided in order to determine the friction force.
It will be invaluable if (when) you need to calculate sample correlation coefficient, but otherwise, it has pretty much no value.
well i would say that a factor is a number add to another number and it equal something but a coefficient is not really what i know but i think its something similar to a factor
You need to know both material involved in the friction to find the coefficient
