This is an expression, not an equation, so it cannot be "solved for x". It can be expanded or simplified.
To expand the expression:
Step 1: Use the distributive property (FOIL method).
(x+2)(3+x)=xβ
3+xβ
x+2β
3+2β
x
Step 2: Perform the multiplications.
=3x+x2+6+2x
Step 3: Combine like terms.
=x2+(3x+2x)+6
=x2+5x+6
The expanded form of the expression is x2+5x+6.
