Find the length of a side of a square if its area is 9ײ+30×+25.

Answer 1

area = 9x²+30x+25
side = √(9x²+30x+25)
= √(3x+5)^2
= 3x+5, where x > -5/3

Answer 2

Since all we know is that 3x+5 > 0, maybe we should consider that
√(3x+5)^2 = |3x+5|
doesn't really matter what x is.

Answer 3

Find the length of a side (s)of a square if it's area (a) is 9ײ+30 ×+25
