Ineed with this i have to use the tabular method which is using like the boxes.

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.

step-by-step explanation:

given : the shape of his satellite can be modeled by   where x and y are modeled in inches.

now,the given equation   is a equation of parabola.

here, coefficient of x is positive, hence the parabola opens rightwards.

on comparing this equation with standard equation , we get

in standard equation, coordinates of focus=(0,m)

thus for given equation coordinates of focus=(0,1.5)
