Answer:
- Infinitely many solutions
Step-by-step explanation:
- 3(x + 10) + 6 = 3(x + 12)
- 3x + 30 + 6 = 3x + 36
- 3x - 3x = 36 - 36
- 0 = 0
This equation has infinitely many solutions as for any value of x we have same result
Answer:

Step-by-step explanation:
<u>Given polynomial is:</u>

![\rule[225]{225}{2}](https://tex.z-dn.net/?f=%5Crule%5B225%5D%7B225%7D%7B2%7D)
First factor is (x-1)
Let x - 1 = 0 => x = 1
Putting this in the above polynomial

Given that it's remainder is 3


Subtracting 7 to both sides

<h2>a + b = -4 -------------------------- (1)</h2>
![\rule[225]{225}{2}](https://tex.z-dn.net/?f=%5Crule%5B225%5D%7B225%7D%7B2%7D)
Second Factor is 2x + 1
Let 2x + 1 = 0 => x = - 1 / 2
Putting in the above polynomial

The remainder is 6

<h2>-a + 2b = 28 --------------------------------(2)</h2>
![\rule[225]{225}{2}](https://tex.z-dn.net/?f=%5Crule%5B225%5D%7B225%7D%7B2%7D)
Adding both equations
a + b - a + 2b = -4 + 28
3b = 24
Dividing both sides by 3
b = 8
![\rule[225]{225}{2}](https://tex.z-dn.net/?f=%5Crule%5B225%5D%7B225%7D%7B2%7D)
Putting b = 8 in Equation (1)
a + 8 = -4
a = - 4 - 8
a = -12
![\rule[225]{225}{2}](https://tex.z-dn.net/?f=%5Crule%5B225%5D%7B225%7D%7B2%7D)
