10.4 Solve Using Square Root - In-Class Practice

Directions: When solving, you must show

all work on a separate sheet of paper or in Notability.

When typing the answer:

If there are two solutions, type the two solutions like this example: 1 or 2

If there is one solution, type the one solution, like this: 1

If there is no solution, type: no solution

Do you understand the directions? Check all that apply.

• I will show work on a separate sheet of paper or in Notability.

• I will type answers as described:

  Just the numbers; if two answer then something like this: 3.45 or -8.55; if one solutions then just that number and if no solution, then type: no solution.
