Answer:

○ \displaystyle -6x^2 + 6x + 5

Step-by-step explanation:

Since the divisor is in the form of \displaystyle x - c,use what is called Synthetic Division. Remember, in this formula, -c gives you the OPPOCITE TERMS OF WHAT THEY <em>REALLY</em> ARE, so do not forget it. Anyway, here is how it is done:

2| −6 18 −7 −10

↓ −12 12 10

________________

−6 6 5 0 \displaystyle \hookrightarrow -6x^2 + 6x + 5

You start by placing the <em>c</em> in the top left corner, then list all the coefficients of your dividend [−6x³ + 18x² - 7x - 10]. You bring down the original term closest to <em>c</em> then begin your multiplication. Now depending on what symbol your result is tells you whether the next step is to subtract or add, then you continue this process starting with multiplication all the way up until you reach the end. Now, when the last term is 0, that means you have <em>no remainder</em>. Finally, your quotient is <em>one degree less</em> than your dividend, so that −6 in your quotient can be a \displaystyle -6x^2,the \displaystyle 6xfollows right behind it, then you end it off with \displaystyle 5,giving you the quotient of \displaystyle -6x^2 + 6x + 5.

I am joyous to assist you at any time.
