b
Type (ii) The equations of the type ap(x) + p(x) = c

3
Example 2: Solve the equation 2(2x - 1) + 2x - 1 = 5

3
Solution: Given that 2(2x - 1) + 2x - 1 = 5 (i)
Let 2x - 1 = y.
Then the equation (i) becomes

Version 1.1 Type (iii) Reciprocal equations of the type:

An equation is said to be a reciprocal equation, if it remains
unchanged, when x is replaced by 1 .

x
Replacing x by 1 ax4 - bx3 +cx2 - bx + a = 0, we have

x
