Answer:

The value of A is 4.

Step-by-step explanation:

Consider the provided quadratic equation.

4x^2-20x+3=0

Subtract 3 from both sides.

4x^2-20x+3-3=-3

4x^2-20x=-3

Now take 4 common from the left side of the above equation.

4(x^2-5x)=-3

Compare the above equation with A(x^2 - 5x) = -3

By the comparison it is clear the value of A is 4.

Hence, the value of A is 4.
