For example if ( m + n + p ) is to be multiplied by ( a + b + c ) , A may be substituted for the multiplicand ( m + n + p ) . Thus : ( a + b + c ) ( m + n + p ) = ( a + b + c ) A = aA bA + CA If ( m + n + p ) is then substituted for its ...

Since we have multiplied by 8 and substituted b for 8a , this process must now be reversed . In other words , substituting 8a for b , we obtain ( 8a - 28 ) ( 8a +6 ) 8 Then , since 4 is a factor of ( 8a - 28 ) , and 2 is a factor of ...
