Question

How many solutions does x^2=9 have

Answer 1

$\huge\text{Hey there!}$

$\mathsf{x^2=9}$

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

$\mathsf{x =\pm \sqrt{9}}$

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

$\mathsf{ - \sqrt{9} = \boxed{\bf -3}}$

$\mathsf{\sqrt{9}=\boxed{\bf 3}}$

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

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

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

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