Question

Please help me in this
factorize- 12(4x-1/4x)²+5(4x-1/4x)-2​

Answer 1

Let (4x - 1/4x) = a.                                                                                          

:. $12a^{2} +5a - 2$

= $12a^{2} + 8a - 3a -2$

= 4a(3a+2) - 1(3a+2)

= (3a+2)(4a-1)

Putting value of a,

(12x - 1/12x + 2)(16x - 1/16x-1)
