Step-by-step explanation:
Assuming your problem is: 
We multiply the top and subtract the bottom, then divide the results together in the calc.
<em>Rounded to 1 decimal place: </em><em>2.4</em>
Answer:
(y - 1)(5y + 3)
Step-by-step explanation:
5y² - 2y - 3
Consider the factors of the product of the coefficient of the y² term and the constant term which sum to give the coefficient of the y- term
product = 5 × - 3 = - 15 and sum = - 2
The factors are - 5 and + 3
Use these factors to split the y- term
5y² - 5y + 3y - 3 ( factor the first/second and third/fourth terms )
5y(y - 1) + 3(y - 1) ← factor out (y - 1) from each term
(y - 1)(5y + 3) ← in factored form
Answer:
-10
-5
5
Step-by-step explanation:
From the answers given, you probably mean f(x) = x^3 + 10x2 – 25x – 250
The Remainder Theorem is going to take a bit to solve.
You have to try the factors of 250. One way to make your life a lot easier is to graph the equation. That will give you the roots.
The graph appears below. Since the y intercept is -250 the graph goes down quite a bit and if you show the y intercept then it will not be easy to see the roots.
However just to get the roots, the graph shows that
x = -10
x = - 5
x = 5
The last answer is the right one. To use the remainder theorem, you could show none of the answers will give 0s except the last one. For example, the second one will give
f((10) = 10^3 + 10*10^2 - 25*10 - 250
f(10) = 1000 + 1000 - 250 - 250
f(10) = 2000 - 500
f(10) = 1500 which is not 0.
==================
f(1) = (1)^3 + 10*(1)^2 - 25(1) - 250
f(1) = 1 + 10 - 25 - 250
f(1) = -264 which again is not zero

Step-by-step explanation:
So as we know, 30/x = 100/80
100/80 = 1.25
Now we have 30/x = 1.25
Multiply both sides of the equation by x - <u>(30/x)x = (1.25)x</u>
Now we have 30 = 1.25x
Divide both sides by 1.25 - <u>30/1.25 = 1.25x/1.25</u>
