Sagot :
Answer:
k is equal to -6
Step-by-step explanation:
(x+4)*(x+2)=[tex]x^{2}[/tex]+6x+8
now since 6 is postive and k is negative 2 negative make a positive so 6 becomes -6
if we substitute -6 to k it becomes x^2+-(-6)x+8=[tex]x^{2}[/tex]+6x+8
this confirms that -6 is the answer
hope this helps
