A) b = - 19Step-by-step explanation:x² - 19x + 18 == x² - x - 18x + 18= x(x - 1) - 18(x - 1)= (x - 1)(x - 18)Reply
11x
Step-by-step explanation:
(x + 2)(x + 9)
x2 + 9x + 2x + 18
x2 + 11x + 18
This is one possibility 🙂
A) b = - 19
Step-by-step explanation:
x² - 19x + 18 =
= x² - x - 18x + 18
= x(x - 1) - 18(x - 1)
= (x - 1)(x - 18)
