Question

y = integration(x square +1) (2x) dx​

Answer 1

Answer:

●( X square + 1)^2 / 2 is your answer

Explanation:

● Sol : -

Integration of ( x square + 1 ) ( 2x) equation 1

let x square +1 is t

then,

x square + 1 = t

diffrentiat both sides w.r.t x

2x dx = dt

then,

dx = dt/2x

putting the value of dx in equation 1

integration of t 2x dt / 2x

then,

integration of t

t square/ 2

putting the value of t

(x square + 1 )^2 /2 ans
