Use synthetic division to solve (2x^34x^2-35x15)/(x-3). What is the quotient?
victus00 [196]
Answer: quotient is 2x^2 + 10x - 5

Solution:

The first polynomial is miswritten.

The right one is: 2x^3 + 4x^2 - 35x + 15.

So, the division is [2x^3 + 4x^2 - 35x + 15] / (x - 3)

The synthetic division uses the coeffcients and obviate the letters, but you have to be sure to respect the place of the coefficient.

So, in this case it is:

3 | 2      4    -35    15
   ---------------------------------
    2     10     - 5      0

So, the quotient is 2x^2 + 10x - 5, and the remainder is 0.

I like to show it in this other way:


   | 2     4     -35     15
   |
   |
3 |       +6    +30     -15
--------------------------------  
    2     10    - 5         0

Of course they are the same coefficients and the answer continue being quotien 2x^2 + 10x - 5, remainder 0.

• What are two ways to start solving this equation? Choose BOTH.
zhannawk [14.2K]

Answer:

Divide both sides by-2

Use the distributive property

Step-by-step explanation:

If you divided both sides by -2, you would get n + 3 = -6.5. Then you would have to subtract 3 from both sides, so n would be -9.5.

However, if you used the distributive property, you would get -2n - 6 = 13. Then you could add 6 to both sides and get -2n = 19. Finally, to solve for n, you would divide both sides by -2 to get n = -9.5.

Hope this helps!
