Answer:

  (d)  7

Step-by-step explanation:

You want to know the value of A that results from transforming 7x²-14x=-6 to A(x²-2x)=-6.

Leading coefficient

When completing the square, it is convenient to factor out the leading coefficient from the variable terms of the quadratic. That is the coefficient of 7x². That coefficient is 7.

  A = 7
