Hey let's go to the library !! I can explain to you.
So explain how to find the zeros using square root property.
So the question asks to find the zeros of (x-7)^2=81
so how do i do that?
This method involves taking the square roots of both sides of the equation. Before taking the square root of each side, you must isolate the term that contains the squared variable.
So tell me the steps Rebecca
So first square root both sides to get rid of the exponent 2. This means square root x-7^2 and doing the same to 81. Eventually it will look like √x-7^2 = √81 this means it will turn into x-7=√81 then you will move 7 to the other side and make it positive. resulting in x= √81+7
