Answer 2

Answer:

We have to find that value(s) of x at which this equation is valid and those values are 0,-2

we can check this

for 0:(0)+2=(0)^2+3(0)+2

2=2

for x=-2: -2+2=(-2)^2+3(-2)+2

0=4-6+2

->LHS=RHS

Step-by-step explanation:

$x + 2 = {x}^{2} + 3x + 2$

${x}^{2} + 2x = 0$

$x(x + 2) = 0$

$x = 0 \: \: \: \: \: or \: \: \: \: \: \: x + 2 = 0$

x=0,-2
