Question

The roots of the quadratic equation 5x² + 7x + 8 = 0

Answer 1

Answer:

Step-by-step explanation:

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

The middle term is,  -7x  its coefficient is  -7 .

The last term, "the constant", is  -8  

Step-1 : Multiply the coefficient of the first term by the constant   5 • -8 = -40  

Step-2 : Find two factors of  -40  whose sum equals the coefficient of the middle term, which is   -7 .

     -40    +    1    =    -39  

     -20    +    2    =    -18  

     -10    +    4    =    -6  

     -8    +    5    =    -3  

     -5    +    8    =    3  

     -4    +    10    =    6  

     -2    +    20    =    18  

     -1    +    40    =    39  

Observation : No two such factors can be found !!

Conclusion : Trinomial can not be factored                                                                   If u understood this answer Mark me as Brainliest
