To solve the polynomial \( x^{2} - 9x + 14 = 0 \), we can factor it. We're looking for two numbers that multiply to \( 14 \) (the constant term) and add up to \( -9 \) (the coefficient of \( x \)). These numbers are \( -7 \) and \( -2 \). So, we can factor the polynomial as follows:
\[
(x - 7)(x - 2) = 0
\]
Setting each factor equal to zero gives us the solutions:
1. \( x - 7 = 0 \) → \( x = 7 \)
2. \( x - 2 = 0 \) → \( x = 2 \)
Thus, the solutions to the equation \( x^{2} - 9x + 14 = 0 \) are \( x = 7 \) and \( x = 2 \).
Now, if you want to check your work, try plugging these values back into the original equation to see if they satisfy it—math is more fun when you double-check your answers!
