Answer 1

Factoring b2 - 13b + 48

The first term is, b2 its coefficient is 1 .
The middle term is, -13b its coefficient is -13 .
The last term, "the constant", is +48

Step-1 : Multiply the coefficient of the first term by the constant 1 • 48 = 48

Step-2 : Find two factors of 48 whose sum equals the coefficient of the middle term, which is -13 .

-48 + -1 = -49
-24 + -2 = -26
-16 + -3 = -19
-12 + -4 = -16
-8 + -6 = -14
-6 + -8 = -14

For tidiness, printing of 14 lines which failed to find two such factors, was suppressed

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



Polynomial Long Division :

1.2 Polynomial Long Division
Dividing : b2-13b+48
("Dividend")
By : b-7 ("Divisor")

dividend b2 - 13b + 48
- divisor * b1 b2 - 7b
remainder - 6b + 48
- divisor * -6b0 - 6b + 42
remainder 6
Quotient : b-6
Remainder : 6

Final result :

b2 - 13b + 48
———————
b - 7


Note : you must simplify :

b2 - 13b + 48
———————
b - 7
