How do you express x^2+5x into the form: a(2x^2+x)+b(3x^2+x)
Sorry. We are supposed to give the hints, so that you can solve the problem your self. You are not showing any attempt on your part.
My hint is very clear.
What is the coefficient of x^2 on right hand side?
What is coefficients of x^2 on the left hand side?
Equate them. That is one equation.
Repeat the same thing for x.
