Finer grained standards that are part of this one

Solve √(6 - x) = x; (√(6 - x))² = x²; 6 - x = x²; x² + x - 6 = 0; (x - 2)(x + 3) = 0; Check 2 and -3 in the original equation: √(6 - 2) = √4 = 2; √(6 - -3) = √9 ≠ -3 Because -3 does not satisfy the original equation, -3 is an extraneous solution. 2 is the only solution to the equation.
