Justify "<span>x2 = 25 is {±5}"
First, please write x^2, not x2.
</span><span>x^2 = 25; solve for x. Take the sqrt of both sides. Must write "plus or minus " in front of the sqrt of 25:
x^2 = 25 becomes x = plus or minus 5, so x: {-5, 5}</span>
The scale factor is 3 because it’s going from 6 to 18, 18/6=3
