Answer:
Hello,
Step-by-step explanation:
If producer means to make factors then
[tex]x^2-4x-5=x^2-4x+4-9\\\\=(x-2)^2-9\\\\=(x-2-3)(x-2+3)\\\\=(x-5)(x+1)[/tex]
(x + 1)(x - 5)
Explanation:
[tex]\sf\rightarrow x^2 - 4x -5[/tex]
breakdown
[tex]\sf\rightarrow x^2 -5x+x -5[/tex]
factor out
[tex]\sf\rightarrow x(x -5)+1(x -5)[/tex]
collect into groups
[tex]\sf\rightarrow (x+1)(x -5)[/tex]
