Question

(0.87)²-(0.13)²
__________
(0.87)-(0.13)​

Answer 1

Answer:

0.87-0.13 right answer

Answer 2

Answer:

(0.87 + 0.13)

Step-by-step explanation:

This can be solved by using the identity a² - b² = (a + b)(a - b)

Here, a = 0.87

b = 0.13

=> (0.87)²-(0.13)² = (0.87 + 0.13)(0.87 - 0.13)

Comparing the question and the above statement, the missing term is (0.87 + 0.13).

Thus the answer is (0.87 + 0.13).
