Question

example of ( a+b ) ( a+b ) = (a^2) - ( b^2 )​

Answer 1

Answer:

The formula is wrong. It should be :

(a+b) (a-b) = (a^2) (b^2)

Step-by-step explanation:

$Let \: \: us \: \: assume, \\ a = 5 \\ b = 3 \\ \\ (a + b)(a - b) = {a}^{2} - {b}^{2} \\ (5 + 3)(5 - 3) = {5}^{2} - {3}^{2} \\ 8 \times 2 = 25 - 9 \\ \large{ \boxed{ \boxed{ \underline{ \underline{16 = 16}}}}}$
