    Answer:

    d. – 3x² – 2x

    Step-by-step explanation:

    You need to get rid of the unnecessary parentheses so you equation lookes like this.

    -x² + 3x – (5x + 2x²)

    Then, you need to multiply out the negative infrom of your remaining parentheses so your eqation lookes like this

    -x² + 3x – 5x -2x²

    Lastly collect like terms.

    -x² + (- 2x²) = – 3x²

    3x – 5x = -2x

    Put them together and bam you have your answer of…

    – 3x² – 2x

    Lots of love,
