Question
Factor 3x3 – 12x2 + 12x
- 3x (x + 2) (x – 2)
- -3x (x + 2) (x – 2)
- 3x (x – 2) (x – 2)
- x (3x – 6)(x + 2)
The correct answer is: 3x (x – 2) (x – 2)
Take out 3x,
3x (x2 – 4x + 4) = 3x((x)2 – 2(x)(2) + (2)2) = 3x (x – 2)2 = 3x (x – 2) (x – 2)

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.
