if f(x)=2x^2+1 and g(x)-x^2-7, find (f+g)(x)

Answer 1

if f(x)=2x^2+1 and g(x)-x^2-7, find (f+g)(x)

Think this way :(f+g)(x)=f(x)+g(x)=(2x²+1)+(x²-7)=3x²-6.

I hope this helps!

Answer 2

To find the solution, you add the polynomials together and combine like terms

(f+g)(x)=(2x²+1)+(-x²-7)

(f+g)(x)=2x²-x²+1-7

(f+g)(x)=x²-6
