The polynomial expressions (-4p2 - 9p + 11) and (p2 - 5p + 4) are subtracted to provide 5p2 + 4p - 7.
From (p2 - 5p + 4) deduct (-4p2 - 9p + 11).
⇒ (p² - 5p + 4) - (-4p² - 9p + 11)
If we condense the phrase, we have
⇒ p² - 5p + 4 + 4p² + 9p - 11
⇒ 5p² + 4p - 7
The polynomial expressions (-4p2 - 9p + 11) and (p2 - 5p + 4) are subtracted to provide 5p2 + 4p - 7.
Algebra is the study of mathematical symbols, and logic is the manipulation of those symbols.One of the earliest areas of mathematics that deals with number theory, geometry, and analysis is algebra. Algebra is also defined as the study of mathematical rules and symbols through the manipulation of those mathematical symbols.
It only denotes taking something away from a person, place, item, etc. Subtraction is the process of removing something from a group or list of possibilities.
