Question

(i) 5x² - 6x - 2 = 0 solve by middle term splitting or factorìsation method ​

Answer 1

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   =   -9   

  -5   +   2   =   -3  

  -2   +   5   =   3    

 -1   +   10   =   9

Observation : No two such factors can be found !! 

Conclusion : Trinomial can not be factored

better you solve it by using quadratic formula....
