Question

(4x4 + 7x2 + 6x) - (x3 - 7x + 10)

Answer 1

Answer:

4x4 - x3 + 7x2 + 13x - 10

Step-by-step explanation:

Answer 2

Answer:

4x4 - x3 + 7x2 + 13x - 10

Step-by-step explanation:

(((4•(x4))+7x2)+6x)-(x3-7x+10)

((22x4 +  7x2) +  6x) -  (x3 - 7x + 10)

3.1    Find roots (zeroes) of :       F(x) = 4x4-x3+7x2+13x-10

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

Rational Roots Test is one of the above mentioned tools. It would only find Rational Roots that is numbers  x  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  4  and the Trailing Constant is  -10.  

of the Leading Coefficient :  1,2 ,4  

of the Trailing Constant :  1 ,2 ,5 ,10

Final result :

 4x4 - x3 + 7x2 + 13x - 10

hope this helps:)sorry if it doesnt
