Question

Factorise.

20x− 26x + 8

Solution

\[\  20 x^2  - 26x + 8\] 

\[ = 20 x^2  - 16x - 10x + 8\] 

\[ = 4x\left( 5x - 4 \right) - 2\left( 5x - 4 \right)\] 

\[ = \left( 4x - 2 \right)\left( 5x - 4 \right)\] 

\[ = 2\left( 2x - 1 \right)\left( 5x - 4 \right)\]

  Is there an error in this question or solution?
