Question
Decide whether each statement is true or false.The equations $x^{2}-4$ and $x+2-4$ are equivalent equations.
Step 1
This can be factored into $(x-2)(x+2)=0$. Setting each factor equal to zero gives us $x=2$ and $x=-2$. So, the solutions to the first equation are $x=2$ and $x=-2$. Show more…

Decide whether each is true or false. If false, correct the right side of the equation. $$x^{2}+x^{2}=x^{4}$$
Review of Basic Concepts
Polynomials
Determine whether each statement is true or false. If the statement is false, make the necessary change(s) to produce a true statement. The equations $\frac{x}{x-4}=\frac{4}{x-4}$ and $x=4$ are equivalent.
