Isoke is solving the quadratic equation by completing the square.10x2 + 40x – 13 = 0 10x2 + 40x = 13 a(x2 + 4x) = 13what is the value of a?

Completing the square is done as follows:

1. Write the equation in a way that the constants are in the right side while the terms with x are on the left. 

2. Make sure that the coefficient of the x^2 term is 1.
10(x^2 + 4x) = 13

3. Adding a term to both sides that will complete the square in the left side. This is done by dividing the coefficient of the x term by 2 and squaring it. Note: The same amount should be added to the right side to balance the equation.
10(x^2 + 4x + 4) =13 +40

10(x+2)^2 = 53

Therefore, the value of A is 10.
