Factors
(x + 12)(x - 4) = 0)
(x - 12)(x + 4) = 0
(x + 4)(x - 12) = 0
(x - 4)(x + 12) = 0
Solutions
x = -12,4
x = -4,12

step-by-step explanation:

given that there are two triangles j'k'l' and jkl>

the former is got by dilating the second one.

when drawn on a grid, (graph paper) coordinates of vertices of first triangle is

(6,12)j, (9,6)k and (12,9)l

side jk has length = distance between j and k

=

side j'k'=distance between j' and k'

=

ie j'k'l' has sides 1/3 of that of corresponding sides of jkl.

hence scale factor of 1/3 is used to get j'k'l'from jkl
