Question

There are (4x4- 20x2y2+25y4 ) students to be arranged in a field during assembly of a school. Find the number of rows and columns in which these students can be arranged such that no student is left out.

Answer 1

Step-by-step explanation:

number of rows and number of students per each are same

number of rows = number of students for each row= a

total number students= (4x4- 20x2y2+25y4 )

a^2= (4x4- 20x2y2+25y4 )

a^2= (2x2- 5y2)^2

a=(2x2- 5y2)

number of rows = number of students for each row = a

= (2x2- 5y2)
