I need help with this please !! I have to use the tabular method which is using like the boxes. Thank you!!
NikAS [45]

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.

I am joyous to assist you anytime.

Brandy is trying to factor the quadratic $3x^2 - x - 10.$ She starts by assuming that the quadratic factors as \[3x^2 - x - 10 =
taurus [48]

Answer:

(B , D) = (-2,5)

Step-by-step explanation:

The given quadratic expression is

3x^{2} -x-10

compare the given expression with ax^{2} +bx+c

so we have a = 3 , b = -1 ,c = -10

now ac=3 (-10)=- 30 and b= -1

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

3x^{2} -6x+5x-10

grouping first two terms and last two terms

(3x^{2} -6x)+(5x-10)

factor out 3x from first two terms and 5 from last two terms

3x(x-2) +5(x-2)          

(x-2)(3x+5)        ( factor out (x-2))

(x+(-2))(3x+5)

hence B =-2 and D= 5

(B,D)= (-2,5)
