Solving Using the Square Root Property
Solve by applying the Square Root Property to a squared binomial that equals a negative number.
Apply the Square Root Property:
Since is not a real number — no real number squared can produce a negative result — the equation has no real solution.
This example extends the no-real-solution outcome from the simpler case (where ) to a squared binomial of the form . The same principle applies: regardless of whether the squared expression is a single variable or an entire binomial, if the constant on the other side is negative, the Square Root Property produces the square root of a negative number, which does not exist among the real numbers. The solving process terminates immediately with no real solution.
