Question

factorize 7√2x^2 -10x - 4√2​

Answer 1

Step-by-step explanation:

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.

here,

7√2 × 4√2 = 56

LCM -- 2 × 2 × 2 × 7

Now,

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

So , by sub

7√2 k² - 14k + 4k - 4√2

7√2 k ( k - √2 ) + 4 ( k - √2 )

( 7√2k + 4 ) ( k - √2 )
