Part 1. create two radical equations: one that has an extraneous solution, and one that does not have an extraneous solution. use the equation below as a model. use a constant in place of each variable a, b, c, and d. you can use positive and negative constants in your equation.

a√(x+b)+c=d

What number should be added to both sides of the equation to complete this square? x^2-10x=7

Given the box plot, will the mean or the median provide a better description of the center? box plot with min at 10.5, q1 at 11.5, median at 12.5, q3 at 13.5, max at 15
