Question

Work with a partner. Use mental math to solve given equations. How many solutions are there for a given equation? Explain your reasoning.

$x^2=0$

Answer 1

Solve the given equation.

$x^2=0$ (Write the equation)

$\Rightarrow \mathrm{x}=\pm \sqrt{0}$ (Take the square root of each side)

$\Rightarrow \mathrm{x}=0$ (Simplify)

So, the solution is $\mathrm{x}=0$.

Hence, there is only one solution for a given equation.
