Solve the following equation:
x^2-6x+9>0
Solve the following equation:
x^2-6x+9>0
To solve the quadratic inequality , we first rewrite the quadratic expression in a recognizable form:
The expression can be rewritten as:
This is a perfect square trinomial, where . We know that a square of a real number is only greater than zero when the number itself is not zero.
Thus, implies , meaning .
Consequently, the inequality holds true for all except .
Therefore, the solution to the inequality is:
