Question

( 1/4x ^2 - 2/5 )( - 1/2x - 2/3 )

find the product

Answer 1

it looks a pain with the fractions

Answer 2

it is

Answer 3

( 1/4x ^2 - 2/5 )( - 1/2x - 2/3 ) = N

(20)( 1/4x ^2 - 2/5 )( - 1/2x - 2/3 )(6) = (20)(6)N

(5x^2- 8)( -3x-4) = 120N ; thats better

Answer 4

5x^2 - 8
-3x -4
---------
-15x^3 +24x
-20x^2 +32
----------------
\(-15x^3-20x^2+24x+32=120N\)

\(\cfrac{-15x^3-20x^2+24x+32}{120}=N\)

Answer 5

split annd reduce as wanted
