Answer:
YES
Step-by-step explanation:
The equation,
, would be an identity if the equation remains true regardless of the value of x we choose to plug in into the equation.
Let's find out if we would always get a true statement using different value of x.
✍️Substituting x = 1 into the equation:
![3(x + 1)2 = (3x + 3)2](https://tex.z-dn.net/?f=%203%28x%20%2B%201%292%20%3D%20%283x%20%2B%203%292%20)
![3(1 + 1)2 = (3(1) + 3)2](https://tex.z-dn.net/?f=%203%281%20%2B%201%292%20%3D%20%283%281%29%20%2B%203%292%20)
![3(2)2 = (3 + 3)2](https://tex.z-dn.net/?f=%203%282%292%20%3D%20%283%20%2B%203%292%20)
(TRUE)
✍️Substituting x = 2 into the equation:
![3(x + 1)2 = (3x + 3)2](https://tex.z-dn.net/?f=%203%28x%20%2B%201%292%20%3D%20%283x%20%2B%203%292%20)
![3(2 + 1)2 = (3(2) + 3)2](https://tex.z-dn.net/?f=%203%282%20%2B%201%292%20%3D%20%283%282%29%20%2B%203%292%20)
![3(3)2 = (6 + 3)2](https://tex.z-dn.net/?f=%203%283%292%20%3D%20%286%20%2B%203%292%20)
(TRUE)
✍️Substituting x = 3 into the equation:
![3(x + 1)2 = (3x + 3)2](https://tex.z-dn.net/?f=%203%28x%20%2B%201%292%20%3D%20%283x%20%2B%203%292%20)
![3(3 + 1)2 = (3(3) + 3)2](https://tex.z-dn.net/?f=%203%283%20%2B%201%292%20%3D%20%283%283%29%20%2B%203%292%20)
![3(4)2 = (9 + 3)2](https://tex.z-dn.net/?f=%203%284%292%20%3D%20%289%20%2B%203%292%20)
(TRUE)
Therefore, we can conclude that the equation,
, is an identity.
