Question

17x^2-18x-2 :- factorise it​

Answer 1

Answer:

Step-by-step explanation:

17x2-18x-2  

Final result :

 17x2 - 18x - 2

Step by step solution :

Step  1  :

Equation at the end of step  1  :

 (17x2 -  18x) -  2

Step  2  :

Trying to factor by splitting the middle term

2.1     Factoring  17x2-18x-2  

The first term is,  17x2  its coefficient is  17 .

The middle term is,  -18x  its coefficient is  -18 .

The last term, "the constant", is  -2  

Step-1 : Multiply the coefficient of the first term by the constant   17 • -2 = -34  

Step-2 : Find two factors of  -34  whose sum equals the coefficient of the middle term, which is   -18 .

     -34    +    1    =    -33  

     -17    +    2    =    -15  

     -2    +    17    =    15  

     -1    +    34    =    33  

Observation : No two such factors can be found !!

Conclusion : Trinomial can not be factored

Final result :

 17x2 - 18x - 2
