What is the factored form of the following expression?
d2 – 14d + 45
A. (d + 9)(d + 5)
B. (d + 9)(d – 5)
C. (d – 9)(d + 5)
D. (d – 9)(d – 5)

Respuesta :

D. (d-9)(d-5)

Since they are both negative, they will multiply to a positive number (45) and add to a negative number (-14)
D. (d – 9)(d – 5) *-*
