Question

Split the middle term 5×^2-6×-2

Answer 1

Answer:

Factoring  5x2 - 6x + 2  

Step-by-step explanation:

The first term is,  5x2  its coefficient is  5 .

The middle term is,  -6x  its coefficient is  -6 .

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

Step-1 : Multiply the coefficient of the first term by the constant   5 • 2 = 10  

Step-2 : Find two factors of  10  whose sum equals the coefficient of the middle term, which is   -6 .

     -10    +    -1    =    -11  

     -5    +    -2    =    -7  

     -2    +    -5    =    -7  

     -1    +    -10    =    -11  

     1    +    10    =    11  

     2    +    5    =    7  

     5    +    2    =    7  

     10    +    1    =    11  

Observation : No two such factors can be found !!

Conclusion : Trinomial can not be factored
