−x)(4x

2

−4x−5)−6

(x

2

−x)[(4x

2

−4x)−5]−6

(x

2

−x)[4(x

2

−x)−5]−6

Let us assume x

2

−x=q

So, q[4q−5]−6

4q

2

−5q−6

4q

2

−8q+3q−6

4q(q−2)+3(q−2)

(q−2)(4q+3)

Now, substitute the value of q

(x

2

−x−2)(4(x

2

−x)+3)

(x

2

−x−2)(4x

2

−4x+3)

(x

2

−2x+x−2)(4x

2

−4x+3)

[x(x−2)+1(x−2)](4x

2

−4x+3)

(x−2)(x+1)(4x

2

−4x+3)
