Answer:

The answer for Factorization is (x+6)(x-2) = 0 or Solving for x is 2 and -6.

Step-by-step explanation:

x² - 12 = -4x

Factorisation :

x² + 4x - 12 = 0

x² - 2x + 6x - 12 = 0

x(x-2)x + 6(x-2) = 0

(x+6)(x-2) = 0

Solve for x :

(x+6)(x-2) = 0

x + 6 = 0

x = -6

x - 2 = 0

x = 2

A transformation maps a onto b and c onto d name the image of a name the preimage of b name the image of c name the preimage of

Doss [256]

the image of $a$ is $b$
the preimage of $b$ is $a$
the image of $c$ is $d$
the preimage of $d$ is $c$
