Answer» are given with TWO equations and a certain question that how much should EQUATION 1 be DECREASED to get equation 2? Equation 1 = a⁴ + 2a² - 3a + 7Equation 2 = a³ + a² + a - 1FOR determining the above decrement by equation 1, we need to subtract Equation 2 from Equation 1:➝ Equation 1 - Equation 2➝ a⁴ + 2a² - 3a + 7 - (a³ + a² + a - 1)➝ a⁴ + 2a² - 3a + 7 - a³ - a² - a + 1Combining the like terms (same degree):➝ a⁴ - a³ + (2a² - a²) + (-3a - a) + 7 + 1➝ a⁴ - a³ + a² - 4A + 8Thus, when Equation 1 is decreased by a⁴ - a³ + a² - 4a + 8, we will get Equation 2. And we are done !!! |
