Question: User: 2x plus 2 squared equals 16 solve
1. **State the problem:** Solve the equation $$2x + 2^2 = 16$$ for $$x$$.
2. **Rewrite the equation:** Recall that $$2^2 = 4$$, so the equation becomes:
$$2x + 4 = 16$$
3. **Isolate the term with $$x$$:** Subtract $$4$$ from both sides:
$$2x + \cancel{4} - \cancel{4} = 16 - 4$$
which simplifies to:
$$2x = 12$$
4. **Solve for $$x$$:** Divide both sides by $$2$$:
$$\frac{2x}{2} = \frac{12}{2}$$
which simplifies to:
$$x = 6$$
5. **Check the solution:** Substitute $$x = 6$$ back into the original equation:
$$2(6) + 2^2 = 12 + 4 = 16$$
The left side equals the right side, so $$x = 6$$ is the correct solution.
