(9h+3)(−h−1) porfavor ayudenme con esta pregunta.
2 answers:
(9h+3)(-h-1)
-9h^2 - 9h -3h -3 = 0
-9h^2 -12h -3 = 0
(h+1)(3h+1) = 0
h = -1, h = -1/3
Answer:
-9h² - 12h - 3
Step-by-step explanation:
Follow the FOIL method:
FOIL = First, Outside, Inside, Last
Multiply the terms together:
First: 9h * -h = -9h²
Outside: 9h * -1 = -9h
Inside: 3 * -h = -3h
Last: 3 * -1 = -3
Combine like terms: 9h² + (-9h - 3h) - 3
9h² - 12h - 3
-9h² - 12h - 3 is your answer.
