Answer:
(x - 9)(x + 8)
Step-by-step explanation:
Given
x² - x - 72
Consider the factors of the constant term (- 72) which sum to give the coefficient of the x- term (- 1)
the factors are - 9 and + 8, since
- 9 × 8 = - 72 and - 9 + 8 = - 1, thus
x² - x - 72 = (x - 9)(x + 8)
Answer:
Para factorizar trinomios de la forma ax2 + bx + c, existen varias formas, a continuación se describirá una de ellas: EJEMPLO. Se multiplica y se divide el trinomio por el coeficiente del primer término. Se resuelve el producto del primero y tercer término dejando indicado el del segundo término.
