Question

Cat face integrala din x+2?
Si integrala din x+2-4?
Vreau doar urmatoarea forma ca dupa stiu

Answer 1

$\int\limits{(x+2)} \, dx = \int\limits{x} \, dx+ \int\limits{2} \, dx = \int\limits{x} \, dx+ 2\cdot \int\limits{1} \, dx =\dfrac{x^2}{2}+2\cdot x+C \\ \\ \\ \int\limits{(x+2-4)} \, dx = \int\limits{(x-2)} \, dx=\int\limits{x} \, dx- \int\limits{2} \, dx = \dfrac{x^2}{2}-2x+C$
