Answer:
a. 12 - 8x - x² + x³
b. 275 - 375x - 351x² + 240x³ + 112x⁴
c. 30 + 37m - m² - 25m³ - 14m⁴ + 3m⁵
d. 81 + 9x² + x⁴
Step-by-step explanation:
Tabular method is what I hear people call "Partial Products". Alright. All you have to do is look at how many terms are in each factor, break them up separately into columns and rows, then do your multiplication. This is the best example you will get, and just so you know, it is NOT drawn to scale [IMPERFECT]:
d.
9 | -3x | x²
------|-------|-----
9 | 81 | -27x | 9x²
____________________
3x | 27x| -9x² | 3x³
| | |
____________________
x² |9x² | -3x³ | x⁴

Add up all the boldfaced terms inside the box, and you will get the above answer.

Answer:
(B , D) = (-2,5)
Step-by-step explanation:
The given quadratic expression is
compare the given expression with 
so we have 
now 
and 
we need to find two numbers such that their product is -30 and sum is -1
-6 and 5 are such numbers
so we have
grouping first two terms and last two terms
factor out 3x from first two terms and 5 from last two terms
( factor out (x-2))
hence B =-2 and D= 5
(B,D)= (-2,5)
