Solve $x^2- 9x + 14 = 0$ .

The answer is $x = 7$ and $x = 2$ .

Factor the left side of the equation.
$(x - 7)(x- 2) =0$

Solve each term in the product separately.
$x - 7 = 0$
Add 7 to both sides.
$x = 7$

$x - 2 = 0$
Add 2 to both sides.
$x = 2$

Check.
$x= 7$
$7^2 - 9(7) + 14 = 0$
$49 - 63 + 14 = 0$

$x = 2$
$2^2 - 9(2) + 14 = 0$
$4 - 18 + 14 = 0$
