State whether the statements are true (T) or false (F).
Common factor of 12a²b²+4ab²-32 is 4.

Let us consider that common factor of 12a²b² + 4ab² – 32 = 4

Check: 12a²b² + 4ab² – 32 = 4 (3a²b² + ab² – 8)

Notice, there are no further common factor in the equation.

Thus, common factor of 12a²b² + 4ab² – 32 is 4.

Hence, the statement is true.

State whether the statements are true (T) or false (F).

x² + (a+b)x + ab = (a+b) (x+ab)

State whether the statements are true (T) or false (F).
