What is the definition of 'distributive property'?

This is what my math teacher had me write down!

answer : distribute property lets you multiply a sum by multiplying each addend separately and then add the products.

example : 5(6+2)= 5×6 +5×2

= 30. + 10

=40

f(2x−x2)=−3x2+6x−1

step-by-step explanation:

set up the composite function and evaluate.

f(2x−x2)=−3x2+6x−1
