Answer 3

To expand the expression -6x(5y - 2x), you need to apply the distributive property. This property states that when you have a term outside the parentheses multiplied by a binomial inside the parentheses, you need to distribute the term to each term inside the parentheses. Here's how you do it:

-6x * (5y - 2x)

To distribute -6x, multiply it by each term inside the parentheses:

-6x * 5y = -30xy -6x * (-2x) = +12x^2 (Note: When you multiply a negative number by a negative number, the result is positive.)

Now combine the two terms:

-30xy + 12x^2

So the expanded form of -6x(5y - 2x) is -30xy + 12x^2.
