Sagot :

Answer:

No solution

Step-by-step explanation:

You can solve this in a few ways. One way is to graph the equation, and the solution is the x-value of the point of intersection. Another way would be to factor, which is more difficult to complete with a square bigger than 2.

By graphing, you can see a parabola that never touches that x-axis, which means no solution.
