answer:To factor the equation x^2 - 8x - 20 = 0, we need to find two numbers that multiply to give -20 and add up to -8. One such pair of numbers is -10 and 2. So we can rewrite the equation as: x^2 - 10x + 2x - 20 = 0 Now we group the terms as follows: (x^2 - 10x) + (2x - 20) = 0 We can factor out x from the first group and 2 from the second group: x(x - 10) + 2(x - 10) = 0 We can simplify this expression by factoring out the common factor of (x - 10): (x - 10)(x + 2) = 0 Therefore, the two solutions to the equation are x = 10 and x = -2.

answer:Jazz music originated in the late 19th and early 20th centuries in New Orleans, Louisiana, USA. It was largely influenced by African American musical traditions, including blues, ragtime, and gospel music. Jazz also drew inspiration from European music styles, such as classical and brass band music. The genre gained popularity in the 1920s and 1930s during the "Jazz Age" and has since evolved and branched out into numerous sub-genres. Jazz has had a significant impact on American and world culture, and its influence can be heard in varying degrees in many forms of music today.
