Question

The area of a square is (4a2 – 20ab + 25b2) sq. units. What is the side of the square?

Answer 1

Answer:

TO FIND THE SIDES YOU HAVE TO FACTORISE IT

S² = 4a²-20ab +25b²

• S² = 4a² (- 10ab -10ab) + 25b²
• S² = 2a (2a - 5b) -5b (2a - 5b)
• S² = (2a - 5b) (2a - 5b)
• S = 2a -5b

Answer 2

Answer:

Step-by-step explanation:

Answer:

TO FIND THE SIDES YOU HAVE TO FACTORISE IT

S² = 4a²-20ab +25b²

S² = 4a² (- 10ab -10ab) + 25b²

S² = 2a (2a - 5b) -5b (2a - 5b)

S² = (2a - 5b) (2a - 5b)

S = 2a -5b
