f(x) 2x^2 + 3x - 1 and g(x) = 3x + 4. Find f • g(x)

Answer 1

For this question I am assuming that you mean f multiplied by g(x) and not the composite of f and g(x). To set this up you just have to do the following (2x^2+3x-1)*(3x+4) from here we just distribute the 2x^2 into 3x+4 and we do that for all of the terms in the first parenthesis so it will look like this. 2x^2(3x+4)+3x(3x+4)-1(3x+4). This simplified turns into 6x^3+8x^2+9x^2+12x-3x-4. We then simplify this to 6x^3+17x^2+9x-4 which is the answer. If I miss interpreted this problem feel free to let me know.
