When integrating, we raise the power by 1 and divide by the new powerSo, 2x5 becomes 2x6 /6 which simplified down as the question asks is x^6/3-1/(4x3) is -(1/4)x^-3 using indices laws, raising the power by one and dividing by the new power gives -(1/4)x-2/(-2) which simplifies down to (1/8)x-2-5 becomes -5xDon't forget when intgrating to add the constant, so putting all this togehter gives us:x6/3 +(1/8)x-2-5x+c
