(g^3+8g-2)+(3g^2-5g+1) and this I need an answer for too (10x+2)(3x+4) My book says I need to simplify these problems and write each answer in standard form but I don't really know how to do that, Can someone answer them and show me the steps they did so I know what to do next time I get questions like these? Oh and I almost forgot this one (7m^2-5m-2)-(-m^2-5m+1)
