Answer:
(x+1)(x-14)(x+3)
Step-by-step explanation:
The first step in factorising polynomials is to find the smallest factor first. The way to do this is with trial and error. Lets see if x+1 is a factor.
According to the factor theorem, (x-a) is a factor of P(x) if and only when P(a) = 0
In this case we will use f(x) = ((x)^3)-((10x)^2)-53x-42
f(-1) = 0
Therefore (x+1) is a factor of the polynomial.
Now we divide the polynomial with (x+1) via long division to get (x^2)-11x-42.
We now factorise (x^2)-11x-42 using whatever method you would like. I'm going to use the AC method, where we find a number that multiplies to AC and adds to B, In this case AC = -42, and B = -11.
Therefore (x^2)-11x-42 factosied is (x-14)(x+3)
Now merge (x+1) with (x-14)(x+3)
The final answer is (x+1)(x-14)(x+3)

Answer:
11 and 16
Step-by-step explanation:
A good way to solve these is to work backwards.
X= larger and Y= smaller
if X is 5 more than 2Y than subtract 5 from the total
38 - 5 = 33
divide by 3
33/3 = 11
11 = Y and double that is 22 so add the five back into X and you get 16
We have been given 4 expressions. We are asked to choose the expressions, which simplifies to 0.
Let us check our given choices one by one.
1. 
When we will subtract 8g from 8g, we will get 0. Therefore, expression simplifies to 0.
2. 
Let us remove parenthesis.
Upon combining like terms, we will get:
Since simplifies to , therefore, expression is not a correct choice.
3. 
Let us remove parenthesis.
Upon combining terms, we will get:
Since simplifies to 0, therefore, expression is a correct choice.
4. 
Let us combine the terms as:
Since simplifies to 
, therefore, expression is not a correct choice.
