Question

Given the area of the square given, factor to find the side length.
Area = 36x2 + 120x + 100

  1. 3x + 10
  2. 5x + 25
  3. 6x + 10
  4. 4x + 36

The correct answer is: 6x + 10


    36x2 + 120x + 100 = (6x)2 + 2(6x) (10) + 102 = (6x + 10)2
    So, the side length is 6x + 10.

    Maria is making a rectangular quilt. She starts with a square of fabric with side length of x cm. She adds some fabric to one side of the square and a different amount of fabric to an adjacent side of the square. Her final quilt has an area of x2 + 13x + 30 cm2. How much longer is the long dimension of the quilt than the short dimension?

    In mathematics, factorization or factoring consists of writing a number or another mathematical object as a product of several factors, usually smaller or simpler objects of the same kind.
