Answer:
scale factor: 3
Step-by-step explanation:
For this I will take both A and A' points. So A is (2,2) and A' is (6,6) and since the shape increased in size that means our scale factor must be greater than 1. So all that we have to do is know is how did we get from this x value to that x value or in other words 2 times what equals 6 and it's 3. Then we would do the same for the y value but since it would be the same 2 times what equals 6 and it's still 3 so 3 is the scale factor.
2x^2 + 6x - 12 - 2x + 14x^2 +4
like terms are terms that have the same variable. for example in the expression i have provided as an example, 2x^2 and 14x^2 would be like terms. you can only combine those with like variables, its the same with constants. constants are the terms without a variable, like -12 and 4, those two can be combined because they both don't have a variable like the other terms. lets take my example, the 2x^2 and the 14x^2 combine to make 16x^2, the 6x and -2x combine to make 4x, and the -12 and 4 combine to make -8. always put your answer in standard for unless told otherwise. your answer would be : 16x^2 + 4x - 8 .

But besides that, thinking about math and such from a different view can sometimes make it more efficient in the long run. Algebra and Geometry become nothing once you get them down to a science, it just comes down to practice.
PS, I could've reported this, but decided to give it a shot because I might be saving you some thinking here. If you got more questions, don't hesitate to ask and I will give you a full answer and explanation if it'll help you get through. Let me know! =)
