5sqrt(5)x^2+20x+10x+8sqrt(5)
=sqrt(5)x[5x+4sqrt(5)]+2[5x+4sqrt(5)]
=[sqrt(5)x+2][5x+4sqrt(5)]
=sqrt(5)x[5x+4sqrt(5)]+2[5x+4sqrt(5)]
=[sqrt(5)x+2][5x+4sqrt(5)]

First step multiply co eff of x^2 and constant, So 200
Second step: Factorizing 200 in such a way their sum is 30. So 20 and 10
Third step: Divide the factors by co eff of x^2 ie 5./5
So 20/5./5 and 10/5./5. Simplified as 4/./5 and 2/./5
For arriving the right factors let us change second one as 2./5 / 5
Now factors in simplified are as 4/ ./5 and 2./5 / 5
Now multiply the dr by x and stick on with the nr
So factors would come as ./5 x + 4 and 5x+2./5
