Given f(x)=3x2+4x and g(x)=2x2−x+1 . what is (f+g)(x) ? x^2+5x−1 −x^2−5x−1 5x^2+3x+1 6x^2−4x+1

The value of (f+g)(x), Given f(x)=3x²+4x and g(x)=2x²−x+1  is 5x²+3x+1

Note that, (f+g)(x) is can also be expressed as f(x)+g(x).

⇒ From the expression,

⇒ Then,

⇒ Collecting like terms

Hence, The right answer is 5x²+3x+1

Therefore, The value of (f+g)(x), Given f(x)=3x²+4x and g(x)=2x²−x+1  is 5x²+3x+1
