Question

Factorise the expression and divide (y2
+7y+10) ÷ (y+5)

Answer 1

y2+7y+10
y2+2y+5y+10
y(y+2)+5(y+2)
(y+2)(y+5)
Then divided by y+5
So y+2 is the answer

Answer 2

Answer:

y + 2

Step-by-step explanation:

y^2 + 7y + 10

= y^2 + 2y + 5y + 10

= y ( y + 2 ) + 5 ( y + 2 )

= ( y + 2 ) ( y + 5 )

( y^2 + 7y + 10 ) ÷ ( y + 5 )

= ( y^2 + 7y + 10 ) / ( y + 5 )

= [ ( y + 2 ) ( y + 5 ) ] / ( y + 5 )

= y + 2
