Choose the correct simplification of (2x^3 + x^2 − 4x) − (9x^3 − 3x^2).
\n" ); document.write( "I think the answer is A but im not so sure
\n" ); document.write( "A: 11x^3 − 2x^2 − 4x
\n" ); document.write( "B: −7x^3 + 4x^2 − 4x
\n" ); document.write( "C: −2x^3 − 2x^2 − 4x
\n" ); document.write( "D: −7x^3 − 4x^2 − 4x\r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "(2x^3 + x^2 - 4x) - (9x^3 - 3x^2)
\n" ); document.write( "2x^3 + x^2 - 4x - 9x^3 + 3x^2 (distributed the -1 into the last 2 terms)
\n" ); document.write( "2x^3 - 9x^3 + x^2 + 3x^2 - 4x (grouped like terms together)
\n" ); document.write( "-7x^3 + 4x^2 - 4x (simplified)\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "the answer is not A, it is B
\n" ); document.write( " \n" ); document.write( "
\n" );
