If we write down (2)^{2} = 3(2), we're lying. Sorry. We'll never do it again. Let's figure out, without lying, if *x* = 2 is a solution to the equation. First evaluate the left-hand side expression for *x* = 2: (2)^{2} = 4 Then evaluate the right-hand side expression for *x* = 2: 3(2) = 6 Because 4 doesn't equal 6, *x* = 2 is not a solution to the equation *x*^{2} = 3*x*. Ah. It feels oh-so-much better to arrive at the answer honestly, doesn't it? |
