    7√2k² - 10k - 4√2

    => For factorising with the help of middle term splitting

    we have to multiply the coefficient of k² and constant term.

    7√2 × 4√2 = 56

    LCM -- 2 × 2 × 2 × 7

    Now, we have to split 56 either by adding or by subtracting.

    7√2 k² - 14k + 4k - 4√2

    7√2 k ( k - √2 ) + 4 ( k - √2 )

    ( 7√2k + 4 ) ( k - √2 )
