Question 62250
{{{-4x^2(5x^4-3x^2+x-2)}}}  Distribute the -4x^2 to every term in the parentheses.
{{{-4x^2(5x^4)-4x^2(-3x^2)-4x^2(x)-4x^2(-2)}}}  Multiply the coeffiecients and add the exponents of the variables.
{{{-4*5x^(2+4)-4*-3x^(2+2)-4x^(2+1)-4*-2x^2}}}
{{{highlight(-20x^6+12x^4-4x^3+8x^2)}}}
Happy Calculating!!!
