Factorise: y2 + 10y + 24

1.	Factorise: y2 + 10y + 24
Answer» First find the two numbers whose sum =10 and product = 24 Clearly, the numbers are 6 and 4 ∴ we get, y² +10y + 24 = y²+ 6y + 4y + 24 = y(y+6) + 4(y+6) = (y+4) (y+6)

Answer»

First find the two numbers whose sum =10 and product = 24

Clearly, the numbers are 6 and 4

∴ we get, y² +10y + 24

= y²+ 6y + 4y + 24

= y(y+6) + 4(y+6)

= (y+4) (y+6)
