The "divisor" in synthetic division is most conveniently the value of the zero of the binomial term. Here, that is x=5. You also need to make sure you include all of the coefficients in the "dividend", putting zero where terms are missing.
The appropriate choice is
A.
(x + 2) = 3
-2 -2
0 1
x = 1
Answer:
#1 = 0.75
#2 =0.4
#3 = 1/5
#4 = 9/20
Hope this helps :)
Step-by-step explanation:
Step-1 : Multiply the coefficient of the first term by the constant <span> <span> 6</span> • -1 = -6</span>
Step-2 : Find two factors of -6 whose sum equals the coefficient of the middle term, which is <span> -5 </span>.
<span> -6 + 1 = -5 That's it</span>
Step-3 : Rewrite the polynomial splitting the middle term using the two factors found in step 2 above, -6 and 1
<span>6y2 - 6y</span> + 1y - 1
Step-4 : Add up the first 2 terms, pulling out like factors :
6y • (y-1)
Add up the last 2 terms, pulling out common factors :
1 • (y-1)
Step-5 : Add up the four terms of step 4 :
(6y+1) • (y-1)
Which is the desired factorization
Final result :<span> (y - 1) • (6y + 1)</span>
1. Subtract 2c from both sides to get 3c - 3 = 6.
2. Add 3 to both sides to get 3c = 9.
3. Divide both sides by 3 to get c = 3.
4. The answer is 3.
