Answer:
- Only a factor of 6 was removed from the second term. A factor of 6x should have been removed.
- 6x(5 -2y)
Step-by-step explanation:
The distributive property lets you apply a multiplier to a group of terms. The entire multiplier is applied to each and every term. When making use of this property to rewrite expressions, one must make sure the rewritten expression is completely equivalent to the original.
... 30x -12xy = 6x·5 -6x·2y = 6x(5 -2y)
_____
6x(5 -2xy) = 30x -12x^2y ≠ 30x -12xy
The second term in parentheses has a factor of x that shouldn't be there.
