Answer:

Step-by-step explanation:
The synthetic division can be used to divide a polynomial function by a binomial of the form x-c, determining zeros in the polynomial.
step 1: Establish the synthetic division, placing the polynomial coefficients in the first row (if any term does not appear, assign a zero coefficient) and to the extreme left the value of c.
1 | 1 0 0 1
step 2: Lower the main coefficient to the third row.
1 | 1 0 0 1
1
Step 3: Multiply 1 by the main coefficient 1.
1 | 1 0 0 1
1
1
step 4: Add the elements of the second column.
1 | 1 0 0 1
1
1 1
step 5: Then repeat step 4 until the constant term 1 is reached.
1 | 1 0 0 1
1 1 1
1 1 1 2
step 6: Enter the quotient and remainder
quotient: 
remainder: 2
Solution:

Step-by-step explanation:


30x = 9(2x+6)
30x = 18x+54
30x-18x = 54
12x = 54
x = 54/12
= 27/6
