Weegy: -2x^(5)+2x^(4)-3x^(3)+2 is the answer......(-4x^(5)+9x^(4)-8x^(3)+8)+(2x^(5)-7x^(4)+5x^(3)-6)
Remove the parentheses that are not needed from the expression.
-4x^(5)+9x^(4)-8x^(3)+8+2x^(5)-7x^(4)+5x^(3)-6
Since -4x^(5) and 2x^(5) are like terms, [ subtract 2x^(5) from -4x^(5) to get -2x^(5).
-2x^(5)+9x^(4)-8x^(3)+8-7x^(4)+5x^(3)-6
Since 9x^(4) and -7x^(4) are like terms, add -7x^(4) to 9x^(4) to get ... (More)
