Identify whether the given mathematical statement is correct or not
5 x + 4y = 9xy

• CORRECT

• NOT CORRECT

Answer explanation

The given mathematical statement is NOT CORRECT because the left side of the equation has a variable 'x' and 'y' while the right side has 'xy'.

Factorise the expression 8x - 4xy + 12y

• 4(2x - xy + 3y)

• 4(2x - 3xy + 3y)

• 4(2x - xy - 3y)

• 4(2x - 3xy - 3y)

Answer explanation

The expression can be factorized as 4(2x - xy + 3y). This choice correctly distributes the common factor 4 and includes all the terms in the expression.
