A = (t +10)² = t² +20t +100
B = (5p+4)² = 25p² +40p +16
C = (5x + 2)² = 25x² +20x +4
D = (4x + 7)² = 16x² + 56x +49
E = (x-8)² = x² - 16x +64
F = (4y-1)² = 16y² - 8y +1
G = (3x-7)² = 9x² - 42x +49
H = (6-9w)² = 36 - 108 w + 81w²
I = (5-y)(5+y) = 25 - y²
J = (3x+5)(5x-5) = 9x² -25
K = (10-7z)(10+7z) = 100 - 49z²
L = (5+4g)(5-4g) = 25 - 16g²
