    you should break the question down into different parts. So the first term is 4x multiplied by 2x^2

    This problem involves the distributive property. You need to multiply the term outside the parentheses, 4x, by each term inside the parentheses, 2x^2, -7x, and 3.

    In order to multiply two terms, you need to multiply together the number parts, and multiply together the variables. For example: 2x * 4x = 2 * 4 * x * x = 8x^2 3x^2 * 6x^3 = 18x^5

    first, multiply the numbers, so 4 x 2 = ?
