  1. The area of a rectangular piece of fabric has 17. The area of a sports court is represented by an area of x^2 + 11x + 10. Find the dimensions. c^2 – 12c + 32. Find the dimensions.
  2. The area of pool is represented by w^2 – 5w = 36 19. The area of a patio is represented by w^2 + 3w = 40 where w represents the width. Find the width where w represents the width. Find the width (Remember – you cannot have a negative measurement ) (Remember – you cannot have a negative measurement )

Solve the equation to find the zeroes. Look to factor out a GCF 1
