Answer:

If you're in Alg 1 or IM 1 like 7th-9th grade or so the answer maybe "no solution" If you're in Alg2 or IM2 or IM3 you can solve this. See image.

Explanation:

Get the variable by itself by subtracting 49 from both sides. Use the fact that the sqrt of -1 is the imaginary number, i (yes, in math the imaginary number is a real thing, lol)

Solve x2+49=0 using any method x=____ and x=_____-example-1
