This leaves us with 5x2 = -1. Then, we divide both sides by 5 to isolate x and get a number on the right side, giving us x2 = -1/5. From there, we take the square root of both sides to get x alone, resulting in x = +/-√(-1/5). However, we know from the imaginary number system that the square root of a negative number is an imaginary number, making it invalid in this equation. Therefore, the only real and valid solution for x is positive 1/4 (B). Choice A is incorrect because it does not account for the + or - in
