MATH 1ST QUARTER

• Geometric mean


  The square root of the product of two numbers
• Common ratio


  The ratio between consecutive terms in a geometric sequence
• Synthetic division can also be used to find the remainder
• Arithmetic general formula- an=a +(n-1)d
• Long division

  •step 1- arange the polynomials

  •step 2- divide the 1st term to dividend

  •step 3- multiple the divisor by the first term of the quotient

  •step 4-subtract the product from the divident
