k = 5
the equation of a parabola in vertex form is
y = a(x - h)² + k
where (h, k ) are the coordinates of the vertex and a is a multiplier
To obtain this form use the method of completing the square
Since the coefficient of the x² term is 1 then
add/ subtract (half the coefficient of the x-term )² to x² - 6x
f(x) = x² + 2(- 3)x + 9 - 9 + 14 = (x - 3)² + 5 → k = 5

Answer:
Hence the expression 
Step-by-step explanation:
Explanation
- The given expression is (m+11)(m-4).
- We have to multiply the given expression.
- Multiply the (m+11) by -4, multiply the (m+11) by m then add like terms.
