Tpy6a [65]

Answer:

Remainder: 10

Step-by-step explanation:

Given: (3x^4+2x^3-x^2+2x-14)\div (x+2)

We need to find the remainder of the division polynomial.

Using synthetic division:

-2  |  3        2       -1        2       -14     |

                -6        8      -14       24

       3       -4        7      -12        10

Please see the attachment for steps.

At last we get a number 10.

Therefore, 10 is remainder of division.

If the first equation is multiplied by 3 and then the equations are added, the result is _____.
alina1380 [7]
To practice, what if the two are added now? lets add one term at a time. first the x terms. 3x+x= 4x. then y+-3y=-2y. finally 3+-2=1. now putting them together we get 4x-2y=1.

multiplying the first equation by 3 gets us 9x+3y=9. basically multiplying each term by 3. now just do the same thing from the first part, so start with the new 9x+x and continue
