The solution for this question would be. x += 5 hope it helps, and im truly am sorry if its incorrect!
For me personally, the easiest way to do this is by isolating the x² term, and finding the square root of both sides. The hardest way (well actually, the longest way) would be to use the quadratic formula. It just complicates things unnecessarily.
What are we supposed to do....
the answer is -8. have a nice day!⭐️
