Answer 2

Answer:

Step-by-step explanation:

20x² -9x+1

In this case we need 2 numbers whose product =20 and by adding or substracting we get 9

These 2 numbers will be 5 and 4

as 5 × 4= 20

and

-5 -4= -9 (as in the question -9x is given)

so 20x² - ( -5- 4)x +1

=  20x²-5x - 4x + 1

= 5x (4x-1) - 1 ( 4x-1)

= (5x-1) (4x-1) are the factors.
