The key idea here is that (√10 - 3)(√10 + 3) = 1. The intended answer, and the one most pertinent to the specifics of this problem, is to change the - to a + on one side, and reciprocate that whole side, making: √10 - 3 = 1/(√10 + 3) Of course, the parentheses () will not be used in the actual drawing, but they are needed to clarify the above equation. Other, more trivial solutions were suggested, such as multiplying either side by 1, or changing the 3 into |-3| (the absolute value of -3).
