Question

I = 9x² + 36xy + 36y² ;
II = 4m² - 20m + 25
III = 4x²+ 12x + 9 ;
IV=25a² - 60ab +36b²

a) I = (3x + 6y)²; II = (2m - 5)²;
M = (2x + 3)²; IV = (5a - 6b)²
b) I = (3x - 6y)²; II = (2m + 5)²;
III = (2x + 3)²; IV = (5 - 65)²
c) I = (x + 3y)² ; II = (2m - 5)²;
TII = (2x - 3)²; IV = (5a + 6b)²
d) I = (3x - 6y)?; II = (5m + 2)²;
III = (2x - 3)²; IV = (5a + 6)²​
