Answer:Value of A = 10

Step-by-step explanation:Here Isoke is solving the quadratic equation by completing the square

10x² + 40x – 13 = 0

10x² + 40x – 13 + 13 = 0 + 13

10x² + 40x + 0 = 13

10x² + 40x = 13

10 ( x² + 4x) = 13

Here it is given as

A(x² + 4x) = 13

Comparing both

We will get A = 10

Value of A = 10

Step-by-step explanation:10 is the value of A ……
