Use synthetic division to solve (2x3+4x2 – 35x+15) +(x-3). What is the quotient?
lesya692 [45]

Given:

(2x^3+4x^2-35x+15)\div (x-3)

To find:

The quotient by using the synthetic division.

Solution:

We have,

(2x^3+4x^2-35x+15)\div (x-3)

Here,

Dividend = (2x^3+4x^2-35x+15)

Divisor = x-3

The coefficient of dividend are 2, 4, -35, 15. Write the coefficients of the dividend on the top row and we need to use 3 as divisor for synthetic division. The synthetic division is show below:

3 | 2\quad \quad 4\quad \quad -35\quad \quad 15\\\quad{}\quad{} \quad \quad \ 6\quad \quad \ \ \ 30\quad  -15\\\overline{\quad 2\quad \quad 10\quad \quad -5\quad \quad 0\ \ \ }

The bottom row represents the coefficients of quotient but the last element of bottom row is the remainder.

Degree of dividend is 3 and degree of division is 1. So, the degree of quotient must be 3-1=2.

The quotient is 2x^2+10x-5 and the reminder is 0.

Therefore, the correct option is D.

We need to convert 2 kilograms into pounds. First, we find how many pounds are in 1 kilogram.

There are about 2 pounds in one kilogram.

Then we multiply 2 pounds by 2 kilograms to convert the 2 kilograms into pounds.

2 * 2 = 4

So, the answer to this question is 4 pounds.
