Question

solve 3x square - 2x + 7 = 0 check when thear roots equal .​

Answer 1

Answer:   Factoring  3x2-2x-7  

The first term is,  3x2  its coefficient is  3 .

The middle term is,  -2x  its coefficient is  -2 .

The last term, "the constant", is  -7  

Step-1 : Multiply the coefficient of the first term by the constant   3 • -7 = -21  

Step-2 : Find two factors of  -21  whose sum equals the coefficient of the middle term, which is   -2 .

     -21    +    1    =    -20  

     -7    +    3    =    -4  

     -3    +    7    =    4  

     -1    +    21    =    20  

Observation : No two such factors can be found !!

Conclusion : Trinomial can not be factored
