Integrating with the Power Rule for Integration, Integration of a Constant Rule, and _ dx = In ( 1 x 1 ) + c x respectively, we have: 15 xax+ / 2 ax + / Idx= x2 5 + X + In (1 x1 ) 2 Step 5 Next, we use the Fundamental Theorem of Integral Calculus, (F( x ) dx = F ( x ) = F ( b ) - F ( a ) , a to find the definite integral: 1 + 2x + In (1x1 ) 1 + 2( - 2 + In - In
