Simplify the expression.

(5 x - 1)(x**2 + 4 x - 3) =

If

(5 x - 1)(x**2 + 4 x - 3)

mean

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

then

( 5 x - 1 )( x ^ 2 + 4 x - 3 )=

5 x * x ^ 2 + 5 x * 4 x + 5 x * ( - 3 )

- 1 * x ^ 2 - 1 * 4 x - 1 * ( - 3 ) =

5 x ^ 3 + 20 x ^ 2 - 15 x - x ^ 2 - 4 x + 3 =

5 x ^ 3 + 19 x ^ 2 - 19 x + 3
