Respuesta :

5b²-4b+6 Final result : 5b² - 4b + 6

Step by step solution :Step  1  :
Equation at the end of step  1  : (5b² - 4b) + 6
Step  2  :Trying to factor by splitting the middle term

 2.1     Factoring  5b²-4b+6 


The first term is,  5b²  its coefficient is  5

The middle term is,  -4b  its coefficient is  -4 

The last term, "the constant", is  +6 

Step-1: Multiply the coefficient of the first term by the constant   5 • 6 = 30 

Step-2: Find two factors of  30  whose sum equals the coefficient of the middle term, which is   -4 

Observation: No two such factors can be found !! 
Conclusion : Trinomial can not be factored

Final result : 5b² - 4b + 6
