To multiply out the expression 3(x−2), we will apply the distributive property.
-
Multiply 3 by each term inside the parentheses:
3imesx−3imes2
This gives us:
3x−6
Thus, the result of multiplying out 3(x−2) is 3x−6.

To multiply out the expression 2a(a+b), we again apply the distributive property:
-
Multiply 2a by each term inside the parentheses:
2aimesa+2aimesb
This results in:
2a2+2ab
Hence, the result of multiplying out 2a(a+b) is 2a2+2ab.
