EXPLANATION.
As we know that,
Using substitution method in the equation, we get.
Let, we assume that,
⇒ 2x - 1 = t.
Differentiate both sides w.r.t x, we get.
⇒ 2dx = dt.
⇒ dx = dt/2.
Put the values in the equation, we get.
Put the value of t = 2x - 1 in the equation, we get.
In Definite integrals,
First we put the upper limit then we put the lower limit in the equation, we get.
