To solve the equation(x+5)^2 =9, Tyler first expanded the squared expression. Here is his incomplete work:
(x+5)²-9
(x+5) (x+5)=9
x^2+5x+5x+25=9
x²+10x+25=9
1. Complete Tyler's work and solve the equation.
2. Clare saw the equation (x+5)^2=9 and thought, "There are two numbers, 3 and -3, that equal 9 when squared.
This means x+5 is either 3 or it is -3. I can find the values of x from there." Use Clare's reasoning to solve the
equation.
