Answer
$2x^4-x^3-8x^2+11x-4$.
Work Step by Step
The given expression is
$=(x^2-2x+1)(2x^2+3x-4)$
Multiply the second bracket by each term of the first bracket.
$=x^2(2x^2+3x-4)-2x(2x^2+3x-4)+1(2x^2+3x-4)$
Clear the parentheses.
$=2x^4+3x^3-4x^2-4x^3-6x^2+8x+2x^2+3x-4$
Add like terms.
$=2x^4-x^3-8x^2+11x-4$.
