Question

Factor x2 − 4x + 5. (4 points) Prime (x + 5)(x − 1) (x − 5)(x − 1) (x + 5)(x + 1)

Answer 1

1

Step-by-step explanation

1) Prime

2) (x + 5)(x − 1) = x²-1x+5x-5= x²+4x-5

3) (x − 5)(x − 1)= x² -1x -5x +5= x² -6x +5

4) (x + 5)(x + 1) = x² +1x +5x+ 5x = x² +6x+5

It is 1) Prime

Answer 2

prime
