Percent error = (estimate - real number)/(real number) * 100

percent error = (95 - 91)/(91) * 100 = 4.3956%

(ab + cd + ac - bd)(ab + cd - ac + bd)

Step-by-step explanation:

(ab + cd)² - (ac - bd)² ← is a difference of squares and factors in general as

a² - b² = (a + b)(a - b)

Here a = ab + cd and b = ac - bd , then

= (ab + cd + ac - bd)(ab + cd - (ac - bd))

= (ab + cd + ac - bd)(ab + cd - ac + bd)
