Question

Diana wants to decorate her floor with a shaggy pink rug. The area of the square feet. Which of the following could be the dimensions of the room, in feet?

Answer 1

(2y+z) (y+3)

Explanation:

Area of the room is 2y^2 + 6y + yz+ 3z

We apply grouping method

we group first two terms and last two terms

`(2y^2 + 6y) + (yz+ 3z)`

We take out GCf from each group

GCF of 2y^2 + 6y is 2y

GCF of yz + 3z is z

`2y(y+ 3) + z(y+ 3)`

Factor out y+3

(2y+z) (y+3)
