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 )
