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

 A = 10

Step-by-step explanation:

We have given that : A quadratic equation

                                   another equation

To find:  The value of A

Solution: Taking the quadratic equation  

and try to reduce this equation in form of another equation

⇒

Comparing with another equation

we get that 10 takes the place of A

which implies value of A = 10
