Working note:-
firstly find product, 7\/2 × 4\/2 = 56
Factors of 56 = 2,2,2,7
try to make the middle term i.e 10 either by adding or subtracting the factors
it is make like this-- [2×2=4] [2×7=14]
by subtracting, it make 10 (14-4)
Solution:-
7sq.root2x^2 - 10x -4sq.root2
7sq.root2x^2 -14x+4x -4sq.root2
7sq.root2x(x - sq.root2) + 4(x-sq.root2)
(7sq.root2x +4)(x-sq.root2)
HOPE IT WILL BE HELPFUL
