Rahul and Rajesh were asked to subtract 4x - 5 from x² + 3x - 5. Their solutions are given below. Rahul: (x² + 3x - 5) - ( 4x - 5) = x² + 3x - 5- 4x + 5 = x² - x
Rajesh: (x² + 3x - 5) - (4x - 5) = x² + 3x - 5- 4x - 5 = x² - x - 10
Who solved the problem correctly and what was the mistake made by the other?​
