Use synthethic division to divide 4x^3 -6x^2 -23x+10 by x+2
oee [108]

Answer:

4x^2-14x+5

Step-by-step explanation:

To set up this question you set up the problem by taking the first numbers AND their values (i.e., 4x-6 would make 4, -6) and set them up under a L-shaped bracket. Then solve x+2 by setting it equal to zero (x+2=0), it would be x=-2. You then drag down the first number and multiple it by -2, then add it to the second number and so on until you finish. Whatever is left is then written into and equation, with the exponents starting at one less than the original, and the remainder would be put into a fraction over x+2.

Lostsunrise [7]

Answer:

Step-by-step explanation:

first multiply 1 with 2+5i then multiply 2i with 2+5i and you will get

2+5i+4i+10i^2

then in the next step add 4i and 5i you will get 9i

in the next step put i^2=-1 and you will get -10

in the last step just substract 2-10 you will get -8 and 9i
