Answer:

Final result :  

(sorry if this is long)

 a3 - 5a2 + 4a + 5

Step by step solution :

Step  1  :

Equation at the end of step  1  :

 ((4a-(a3))-3)+(((2•(a3))-5a2)+8)

Step  2  :

Equation at the end of step  2  :

 ((4a-(a3))-3)+((2a3-5a2)+8)

Step  3  :

Checking for a perfect cube :

3.1    a3-5a2+4a+5  is not a perfect cube

Trying to factor by pulling out :

3.2      Factoring:  a3-5a2+4a+5  

Thoughtfully split the expression at hand into groups, each group having two terms :

Group 1:  4a+5  

Group 2:  a3-5a2  

Pull out from each group separately :

Group 1:   (4a+5) • (1)

Group 2:   (a-5) • (a2)

Bad news !! Factoring by pulling out fails :

The groups have no common factor and can not be added up to form a multiplication.

Polynomial Roots Calculator :

3.3    Find roots (zeroes) of :       F(a) = a3-5a2+4a+5

Polynomial Roots Calculator is a set of methods aimed at finding values of  a  for which   F(a)=0  

Rational Roots Test is one of the above mentioned tools. It would only find Rational Roots that is numbers  a  which can be expressed as the quotient of two integers

The Rational Root Theorem states that if a polynomial zeroes for a rational number  P/Q   then  P  is a factor of the Trailing Constant and  Q  is a factor of the Leading Coefficient

In this case, the Leading Coefficient is  1  and the Trailing Constant is  5.

The factor(s) are:

of the Leading Coefficient :  1

of the Trailing Constant :  1 ,5

Hope it helps!!

Please help me! I need this answered fast!
ArbitrLikvidat [17]

Answer:

Question 1: A

Question 2: C

Step-by-step explanation:

The answer to question 1 is A. I know this is correct because Max needs to earn 108 dollars for the headphones he wants so the amount of money he earns per hour which is 15, times the amount of hours he needs to work which is x has to be greater than 108. So, the inequality equation has to be 15x > 108 which is answer A.

The answer to question 2 is C. I know this is correct because Felicia has 2 sisters which make 3 sisters in total to pay for the gift. They all pay evenly, so the first part of the equation would be 3x. The cost for the gift is less than 80 dollars, so we write the inequality equation like 3x < 80 which is answer C.

Find the value of X in the parallelogram below.
nignag [31]

Answer:

28

Step-by-step explanation:

In paralellograms, the lengths of the parallel sides are equal to each other

As seen in the figure, the side that is parallel to the side that is represented with x has a length of 28 units, so the value of x is also equal to 28

Which function has zeros at x=-2 and x=5?
Licemer1 [7]

Answer:

x^{2} - 3x - 10

Step-by-step explanation:

To start, lets form our polynomial factors from our zeroes.

x = -2

x + 2 = 0

x = 5

x - 5 = 0

Now lets put these into factored form by moving them into parenthesis and multiplying them with each other!

(x+2)(x-5)

We can start moving them out! I am going to use FOIL, but you could also use distributive or any other method/property.

x · x = x²

x · -5 = -5x

x · 2 = 2x

2 · 5 = 10

Now lets put our terms into our polynomial function, based on the order of the powers.

x^{2} - 3x - 10

We are done! Hope this helps!
