Which quadratic equation is equivalent to (x – 4)2 – (x – 4) – 6 = 0?

Step-by-step explanation:

Posible answers are found

if you square (x-4), open pharenthesis -(x-4) and then combine like terms

x^2 +16-8x -x+4-6 =0

x^2 -9x +14 =0

or  you can substitute (x-4) with another letter like x-4 =a so

a^2 -a -6 =0

f(x) is the value of the function. b is the value of the function when x equals zero or the y-coordinate of the point where the line crosses the y-axis in the coordinate plane.
