Explanation:
To simplify the expression 3 - t(t + 3), we can use the distributive property and simplify further.
Expanding the expression using the distributive property:
3 - t(t + 3) = 3 - t * t - t * 3
Simplifying further:
= 3 - t^2 - 3t
Now, combining like terms:
= -t^2 - 3t + 3
Therefore, the simplified form of the expression 3 - t(t + 3) is -t^2 - 3t + 3.
