Which expression is equivalent to 2x²+(4x-6x²)+9-(6x+3)

2 Answer

  • 2x²+(4x-6x²)+9-(6x+3)
    2x
    ²+4x-6x²+9-6x-3
    2x²-6x²+4x-6x+9-3
    -4x²-2x+6
  • The expression that is equivalent to 2x²+(4x-6x²)+9-(6x+3) is -4x² - 5x + 6

    Given the function 2x²+(4x-6x²)+9-(6x+3)

    On expansion, the expression becomes;

    = 2x²+(4x-6x²)+9-(6x+3)

    = 2x²+4x-6x²+9-6x-3

    Collect the like terms;

    2x²-6x²+4x - 9x +9-3

    -4x² - 5x + 6

    Hence the expression that is equivalent to 2x²+(4x-6x²)+9-(6x+3) is -4x² - 5x + 6
