Polynomials have been in use since 2000 BC by the Babylonians through the years up to present times. Polynomials have been used to figure out quadratics in radicals, geometrical construction, mathematicians to reduce terms, solve cubics geometrically intersecting parabolas, roots of a quadratic. Newton used polynomials to figure things such as gravity and other items that are still in use today for science, space explorations. Polynomials are not only used in science but also in real everyday life. We can add sum of terms, find degrees of polynomials and use these to study population growth. Much of the technological advancement of our times has come from using

Unformatted text preview: polynomial equations. How will you round off? To round a number to any decimal place value, we want to find the number with zeros in all of the lower places that is closest in value to the original number. As with whole numbers, we look at the digit to the right of the place we wish to round to. Note: When the digit 5, 6, 7, 8, or 9 appears in the ones place, round up; when the digit 0, 1, 2, 3, or 4 appears in the ones place, round down. How will you round off 1.19, 1.545, 4499, 1.6 and 1.90? 1.19 - 1 1.545 - 2 4499 - 4499 1.6 - 2 1.90 - 2...

• The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
