Question 178390
The factors of 2 are 1 and 2
Also, 1 + 2 = 3
{{{(x + 2)(x + 1) = x^2 + 3x + 2}}}
{{{(x + 2)(x + 1) = 0}}}
If {{{x = -2}}}, the equation is solved
{{{-2 + 2)(-2 + 1) = 0}}}
{{{0*(-1) = 0}}}
{{{0 = 0}}}
Also, if {{{x = -1}}}, the equation is solved
{{{(-1 + 2)(-1 + 1) = 0}}}
{{{1*0 = 0}}}
{{{0 = 0}}}
{{{x = -1}}} and {{{x = -2}}} are the solutions
