Solve $$\int { \left( x+2 \right) \left( x-1 \right)  } dx$$


SOLUTION
$$\displaystyle\int (x+2)(x-1)\ dx$$
$$=\displaystyle\int (x^{2}+x-2)\ dx$$
$$=\dfrac{x^{3}}{3}+\dfrac{x^{2}}{2}-2x+C$$      Ans.

Q2 Assertion & Reason Hard
ASSERTION

If $$\displaystyle f\left( x \right)=\int _{ 0 }^{ x }{ g\left( t \right) dt } $$, where $$g$$ is an even function and $$f\left( x+5 \right) =g\left( x \right)$$, then $$\displaystyle g\left( 0 \right)-g\left( x \right)=\int _{ 0 }^{ x }{ f\left( t \right)dt } $$

REASON

$$f$$ is an odd function.

  • A. Both Assertion and Reason are correct but Reason is not the correct explanation for Assertion
  • B. Assertion is correct but Reason is incorrect
  • C. Both Assertion and Reason are incorrect
