Given the expression  13x(9y – 12) we are expected to expand the expression to obtain a similar expression given in the options

step two

we proceed by

[tex]= 13x(9y-12)\\\\=(117xy-156x)[/tex]

step three

we proceed to both terms in the expression

bt a common factor which is 39

[tex]\frac{117xy}{39}-\frac{156x}{39}[/tex]
