1 thought on “<br />[tex]98 {y}^{2 } + 168yz + 72 {z}^{2} [/tex]<br />factorise the expression​”

1. To factorise:-

   • 98y²+168yz+72z²

   __________________________

   Solution:-

   By rearranging the given equation:

   => 98y²+72z²+168yz

   Now adjusting it in the form of any algebraic identity.

   => (7√2y)²+ (6√2z)²+2(7√2y)(6√2z)

   Now we can see that this is in the form of a²+b²+2ab=(a+b)² where a=7√2y and b=6√2z.

   So,

   => (7√2y+6√2z)²

   Hence factorised
