2x - 32×5 factorise the following ​

Answer»

Answer:

We NEED to FACTORISE 2x−32x

5

Here we can take 2x common.

Thus we have 2x−32x

5

=2x(1−16x

4

)

Further it can be written as 2x(1−16x

4

)=2x[1

2

−(4x

2

)

2

]

=2x(1−4x

2

)(1+4x

2

)

=2x(1+4x

2

)(1−2x)(1+2x)

Here we used (a

2

−b

2

)=(a+b)(a−b)

Thus factors are 2,x,(1+4x

2

),(1−2x),(1+2x).
