√2 x2 + 7x + 5√2 = 0
Similarly multiply √2 with 5√2 and we get 10
Pairs of 10 are
1*10 = 10 sum 1+ 10 = 11
2*5 = 10 sum 2+ 5 = 7
So our required pair is 2 and 5
√2 x2 + 5x + 2x + 5√2 = 0
x (√2x + 5) + √2(√2x + 5) = 0
(√2x + 5)(x + √2) = 0
√2x + 5 = 0 and x + √2 = 0
x = –5/√2 and x = –√2
–5/√2 and –√2 are our required root of quadratic equation.
