Answer:
c=-0.98
Step-by-step explanation:
We know that the function
[tex]y=x^2+cx^2[/tex]
is solution of the differential equation
[tex]xy'+2y=4x^2[/tex]
to find the value of c we use the condition y(10)=2
[tex]y(10)=(10)^2+c(10)^2=2\\y(10)=100+100c=2\\c=\frac{2-100}{100}=-0.98[/tex]
then, c = -0.98
hope this helps!!
