( x -2 )*( x +3 )
Distributive Law : x*( x +3 ) + -2*( x +3 ) = 0
Commutative Law : ( x^2 +3*x ) + ( -2*x -6 ) = 0
Associative Law : ( x^2 -2*x ) + ( 3*x -6 ) = 0
Distributive Law : x^2 +x -6 = 0
Distributive Law : x*( x +3 ) + -2*( x +3 ) = 0
Commutative Law : ( x^2 +3*x ) + ( -2*x -6 ) = 0
Associative Law : ( x^2 -2*x ) + ( 3*x -6 ) = 0
Distributive Law : x^2 +x -6 = 0

(x - 2)(x + 3)
x^2 + 3x - 2x - 6
x^2 + x - 6.
x^2 + 3x - 2x - 6
x^2 + x - 6.

(x - 2)(x + 3)
= x(x) + x(3) - 2(x) - 2(3)
= x^2 + 3x - 2x - 6
= x^2 + x - 6
= x(x) + x(3) - 2(x) - 2(3)
= x^2 + 3x - 2x - 6
= x^2 + x - 6

x^2 + 3 x - 2 x - 6
x^2 + x - 6
x^2 + x - 6

(x-2) (x+3)
x^2 + (-2+3)x + (-2*3) [identity]
x^2 + x - 6
hope i helped
x^2 + (-2+3)x + (-2*3) [identity]
x^2 + x - 6
hope i helped
