Find the product.Simplify your answer. (-2r)(-3r) square

To find the product of $(-2r)(-3r)$, we need to multiply the coefficients and then multiply the variables.<br /><br />Step 1: Multiply the coefficients.<br />$(-2) \times (-3) = 6$<br /><br />Step 2: Multiply the variables.<br />$r \times r = r^2$<br /><br />Putting it all together, we have:<br />$(-2r)(-3r) = 6r^2$<br /><br />Therefore, the simplified answer is $6r^2$.
