Let w^2 = a

and x = b

8a^2 - 10ab + 3b^2

Find factors of 24 which add up to -10

( -6) ( -4)

8a^2 - 6ab - 4ab + 3b^2

2a ( 4a - 3b) - b ( 4a - 3b)

( 2a - b) ( 4a - 3b)

( 2w^2 - x) ( 4w^2 - 3x ) ANSWER

(8w^2-10xw+3x)^2

= 8w^4 - 6xw^2 - 4xw^2 + 3x^2

= 2w^2(4w^2 - 3x) - x(4w^2 - 3x)

= (2w^2 - x)(4w^2 - 3x)
