How many solutions does x^2=9 have

Question 1

Question 2

Answer:

Your answer is 1

Explanation:

3² = 9 is the only possible solution.

Question 3

$\huge\text{Hey there!}$

$\mathsf{x^2=9}$

$\large\text{TAKE the SQUARE ROOT}$

$\mathsf{x =\pm √(9)}$

$\large\text{REMEMBER this symbol }\mathsf{\pm}\large\text{ means plus or minus}$

$\mathsf{ - √(9) = \boxed{\bf -3}}$

$\mathsf{√(9)=\boxed{\bf 3}}$

$\large\text{OR YOU COULD SAY THIS TO MAKE THIS SIMPLER TO}\\\large\text{SOLVE}\downarrow$

$\large\text{-3}\mathsf{^2= \boxed{\bf -9}}$

$\large\text{3}\mathsf{^2}\large\text{= \boxed{\bf 9}}$

$\boxed{\boxed{\large\textsf{Therefore, your answer: \huge \bf x = -3 or x = 3 }}}\huge\checkmark$

$\large\text{Good luck on your assignment and enjoy your day!}$
