Answers

  1. The simplification of the expression -3x^2(5x – 4x^2 – 6) is -15x^3 + 12x^4 + 18x^2.
    According to the given question.
    We have an expression
    -3x^2(5x – 4x^2 – 6)
    To simplify the above expression we will use distributive law.
    Distributive law relate the operations of multiplication and addition, stated symbolically as a(b + c) = ab + ac.
    Therefore,
    The simplification of the expression -3x^2(5x – 4x^2 – 6) is give by
    -3x^2(5x) -3x^2(-4x^2) -3x^2(-6)
    = -15x^3 + 12x^4 + 18x^2
    Hence, the simplification of the expression -3x^2(5x – 4x^2 – 6) is -15x^3 + 12x^4 + 18x^2.
