Question

the area of a rectangle isײ+9×+18 if it's breatdh is (×+6),find its length​

Answer 1

Step-by-step explanatio

Answer 2

Answer:

x+3

Step-by-step explanation:

area = length x breadth

x^2 + 9x + 18 = (x+6 )×( length)

now factorise x^2 + 9x + 18

x^2 + 3x + 6x + 18 = (x+6 )×( length)

(x+3) × (x+6) = (x+6 )×( length)

therefore length = x+3
