<span>Part A: First, we factor out a^2 to obtain: a^2 [5x^2 - 19x - 4] = a^2[(5x+1)(x-4)]
Part B: By inspection, we can use the factors (x+7)(x+7). To check that we have indeed chosen correctly, we will multiply our factors to obtain x^2 + 7x + 7x + 49 =
x^2 + 14x + 49 = 0, which is correct.
Part C: Again, we can use trial and error and try the factors (x+10)(x-10). Multiplying throughout, we obtain x^2 + 10x - 10x - 100 = x^2 -100.</span>
DescriptionThe Fifteenth Amendment to the United States Constitution prohibits the federal government and each state from denying a citizen the right to vote based on that citizen's "race, color, or previous condition of servitude."

Answer: Honorary events are sorted from oldest to youngest.
Explanation:
- The Romans removed the last Roman king from power and set up a republic. Between 534 and 509 BC, the last Roman king ruled, after which a republic was established. The last king is thought to have been Tarquinius Superbus. History treats him as a tyrant who fiercely dealt with his subjects. In these circumstances, the people stood up against him and removed him from power.
- Thus ended the kingdom period, and a republic was formed. Julius Caesar became the dictator of Rome. It is probably the most celebrated figure in Roman history. After defeating Pompey 46 BC, he was proclaimed dictator. Due to political concerns, he was killed in the assassination. His dictatorship is the first symptom of the disappearance of the republic and the establishment of an empire. So chronologically, this event is the second oldest on the list.
- The "Pax Romana" period in Roman history represents the period of the disappearance of the republic, or the proclamation of Rome as an empire. Historians most often take the year 27 BC to begin the period of the empire. This reshuffle in the country is most commonly associated with Octavian. During the realm, Rome would reach its most enormous territorial scope. Rome will be an empire until the fall of 476 AD.
- The edict of Milan issued to allow Romans to adopt Christianity. The youngest event on this list is the Milan Edict. A game that happened in 313 in the Italian city of Milan. Namely, until that moment, Christians were persecuted throughout the empire. Emperor Constantine allowed the freedom of religion to be edified so that Christianity became a free religion. By the end of the century, Christianity would also become the official religion in Rome.
The Cartesian plane was invented in the 17th century by Rene Descartes.
