Question

quadratic term of x2-x-3=0​

Answer 1

Step-by-step explanation:

Factoring  x2-x-3 

The first term is,  x2  its coefficient is  1 .

The middle term is,  -x  its coefficient is  -1 .

The last term, "the constant", is  -3 

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

Step-2 : Find two factors of  -3  whose sum equals the coefficient of the middle term, which is   -1 .

     -3   +   1   =   -2    

 -1   +   3   =   2

Observation : No two such factors can be found !!
