# If 6 is a root of the equation x^2 - 8x + k= 0, what is the value of k?

k=12
Substitute x=6 in the equation and solve.

#### Explanation:

Since 6 is a root of the equation, it should satisfy the given equation.

${\left(6\right)}^{2} - 8 \left(6\right) + k = 0$
$36 - 48 + k = 0$
$- 12 + k = 0$
$k = 12$
