Question

X2+6x+5=0 by factorisation

Answer 1

x² + 6x + 5

= x² + x + 5x + 5

= x(x+1)+5(x+1)

= (x+5)(x+1)

Solutions for x² + 6x + 5 are x=-1 or x=-5.

Answer 2

Hęřę įš ùř ąńšwęř....♥♡♥

$= > {x}^{2} + 6x + 5$

$= > {x}^{2} + 5x + x + 5$

$= > x(x + 5) + 1(x + 5)$

$= > (x + 1)(x + 5) = 0$

$= > x + 1 = 0$

or

$= > x + 5 = 0$

Hence,x=-1 or x=-5

Hope it helps......
