Question

Write this trinomial in factored form.
8x² - 9x + 1
Enter the correct answar.

Answer 1

Factor out x from 8x^2-x: (8x-1)
8x^2-x

Apply exponent rule: a^b+^c=a^b a^c

x^2=xx
=8xx-x

Factor out common term x
=x(8x-1)
Factor out -1 from -8x+1: -(8x-1)
-8x+1

Factor out common term -1
= -(8x-1)
=x (8x-1)- (8x-1)
Factor out common term 8x-1
=(8x-1)(x-1)

Answer 2

(8x-1) (x-1)

Explanation:

8x² - 9x + 1

(8x - ) (x - )

We know it is minus because we have -9x

We have +1 so both have to be -

To fill in the blanks we put 1

The only combination is 1*1 =1

(8x-1) (x-1)

Lets check

8x^2 -x -8x +1

(8x^2 -9x+1
