(x2+7x-5)/(x-2)
(x^2+7x-5)/(x-2)

Step by Step Solution

Reformatting the input :

Changes made to your input should not affect the solution:

 (1): "x2"   was replaced by   "x^2". 

Step  1  :

            x2 + 7x - 5
 Simplify   ———————————
               x - 2   

Trying to factor by splitting the middle term

 1.1     Factoring  x2 + 7x - 5 

The first term is,  x2  its coefficient is  1 .
The middle term is,  +7x  its coefficient is  7 .
The last term, "the constant", is  -5 

Step-1 : Multiply the coefficient of the first term by the constant   1 • -5 = -5 

Step-2 : Find two factors of  -5  whose sum equals the coefficient of the middle term, which is   7 .

     -5   +   1   =   -4
     -1   +   5   =   4


Observation : No two such factors can be found !!
Conclusion : Trinomial can not be factored

Polynomial Long Division :

 1.2    Polynomial Long Division
Dividing :  x2+7x-5 
                              ("Dividend")
By         :    x-2    ("Divisor")

dividend  x2 + 7x - 5 
- divisor * x1   x2 - 2x   
remainder    9x - 5 
- divisor * 9x0     9x - 18 
remainder      13 

Quotient :  x+9 
Remainder :  13 

Final result :

  x2 + 7x - 5
  ———————————
     x - 2
