Answer:
A = 10
Step-by-step explanation:
We have given that : A quadratic equation [tex]10x^2+40x-13=0[/tex]
another equation [tex]A(x^2+4x)=13[/tex]
To find: The value of A
Solution: Taking the quadratic equation [tex]10x^2+40x-13=0[/tex]
and try to reduce this equation in form of another equation
[tex]10x^2+40x-13=0[/tex] ⇒ [tex]10(x^2+4x)=13[/tex]
Comparing with another equation [tex]A(x^2+4x)=13[/tex]
we get that 10 takes the place of A
which implies value of A = 10
