Factorize: 7√2 x2 – 10x – 4√2.
By splitting the middle term
Step 1 – Multiply 1st and last term
7√2x2 × (–4√2)
–56x2
Step 2 – Find the factors of 56 in such a way that addition or subtraction of that factors is the middle term (–10x).
= 7√2 x2 –14x + 4x – 4√2
= 7√2x (x – √2) + 4 (x – √2)
= (7√2x + 4) (x – √2)
