Simplify the following expression ²+b-1)/(2b-1)-1) - (4-(8/(b+

Step-by-step explanation:

We have to simplify the following expression:

((( b²+b-1 )/( 2b-1 )-1 ) - ( 4-( 8/( b+1 )))

=

={ By simplification of the terms}

= {We have to add those two terms}

= { The L.C.M. is ( 2b-1 )( b+1 ) }

=

= ( Answer )

the image of (6, 9) under a dilation is (4, 6). the scale factor is
