    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
