Step-by-step explanation:
Look it's so simple once you learn it's very easy you have to multiply the 1 and 3rd digit so answer is 5 now you have to find the factors of 5 so
x2 - 4x + 5
x2 - 5x + x + 5
x (x - 5) +1 (x + 5)
(x - 5) (x + 1) are the factors but please recheck the question maybe there is a mistake in sign because my factors x + 5 and x - 5 this should be one sign either positive or negative
