-3m(m + 8)
Expanding the expression gives:
-3m² - 24m
4d(2d + 9)
Expanding the expression gives:
8d² + 36d
To simplify the expression -3m(m + 8), we will apply the distributive property and combine like terms.
Step 1: Distribute -3m to both terms inside the parentheses:
-3m * m = -3m^2
-3m * 8 = -24m
Step 2: Combine the two terms obtained from the distribution:
-3m^2 - 24m
So, the simplified expression for -3m(m + 8) is -3m^2 - 24m.
