Question

urgent .................
y ^ 2 - 1 3 y +4 2 / ( y - 6 )​

Answer 1

Answer:

FIRST THE EQUATION y^2 - 13y + 42 WILL BE FACTORISED...

BY SPLITTING THE MIDDLE TERM,

y^2 - 6y - 7y +42

= y( y-6 ) - 7( y-6 )

= ( y-6 ) ( y-7 )

NOW,

y^2 - 13y +42 / ( y - 6 )

= ( y - 6 ) ( y - 7 ) / ( y - 6 )

= ( y - 7 )
