Find the GCF (Greatest Common Factor)
GCF = 3
Factor out the GCF ( Write the GCF first. Then, in parentheses, divide each term by the GCF)
3(3x^2/3 + -12x/3 - 15/3)
Simplify each term in parentheses
3(x^2 - 4x - 5)
Factor x^2 - 4x - 5
<u>3(x - 5)(x + 1)</u>
This states that a number divided by 3 is 21. the equation is: n/3 = 21

Answer:
200 tiles
Step-by-step explanation:
area of the floor = 2m×4m
the tile=20cm×20cm
the tiles needed to complete the job will be
2m×4m
——–—–
20cm×20cm
change the meters to centimeters
200cm×400cm
————————
20cm×20cm
therefore the answer is 200tiles.
