Exercise: Complete the table below. Provide a standard form of an equation, then give what is asked. The first item serves as your example. Equation Example: x² + 7x = -10 1. 6x + 9 + x² = 0 2. 2x² - 10x = - 18 3. x² +6x + 3 = 0 4.3x² + 4 = 5x Standard Form x² + 7x + 10 = 0 a 1 b 7 C 10 Discriminant b²-4ac Substitute b²-4ac = (7)2² - 4(1)(10) = 49-40 =9 (greater than zero and perfect square number) Nature of the Roots The roots are rational numbers but are equal.​
