<span>
</span>30 + x  thats yhur answer<span>

or

(3x2 + 1) • (x + 3) </span>

Reformatting the input :

Changes made to your input should not affect the solution:

 (1): "x2"   was replaced by   "x^2".  1 more similar replacement(s).

Step by step solution :<span>Equation at the end of step  1  :</span><span><span> (((3 • (x3)) + 32x2) + x) + 3 </span><span> Step  2  :</span></span><span>Equation at the end of step  2  :</span><span> ((3x3 + 32x2) + x) + 3 </span><span>Step  3  :</span>Checking for a perfect cube :

<span> 3.1 </span>  <span> 3x3+9x2+x+3</span>  is not a perfect cube 

Trying to factor by pulling out :

<span> 3.2 </span>     Factoring: <span> 3x3+9x2+x+3</span> 

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

Group 1:  x+3 
Group 2: <span> 3x3+9x2</span> 

Pull out from each group separately :

Group 1:   (x+3) • (1)
Group 2: <span>  (x+3) • (3x2)</span>
               -------------------
Add up the two groups :
              <span> (x+3)  • </span><span> (3x2+1)</span> 
Which is the desired factorization

Polynomial Roots Calculator :

<span> 3.3 </span>   Find roots (zeroes) of :      <span> F(x) = 3x2+1</span>
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  3  and the Trailing Constant is <span> 1. 

 </span>The factor(s) are: 

of the Leading Coefficient : <span> 1,3 
 </span>of the Trailing Constant : <span> 1

La suma de dos número impares consecutivos es 100 . hallar la suma de cifras del mayor<br> numero
gtnhenbr [62]
<h2><u>solución</u></h2>

deja que los números sean x, and x + 2

sabemos que su suma es igual a 100, entonces

  • x + x + 2 = 100

  • 2x = 100 - 2

  • 2x = 98

  • x = 98 ÷ 2

  • x = 49

por lo tanto, el primer número es 49

y el segundo número es x + 2 = 49 + 2 = 51 (también es el mayor entre los dos números)

entonces suma de dígitos de mayor número = 5 + 1 = 6

Respuesta correcta de la pregunta anterior = 6
