Answer 1

Step-by-step explanation:

${a}^{2} - {b}^{2} = ab - {b}^{2} \\ = > (a + b)(a - b) = b(a - b)$

this is the point where it's incorrect.

for example:-

$0 = 0 \\ = > 100 - 100 = 100 - 100 \\ = > 10(10 - 10) = {10}^{2} - {10}^{2} \\ = > 10(10 - 10) = (10 - 10)(10 + 10) \\ = > 10 = 20 \: (this \: step \: is \: wrong) \\ = > 1 = 2$
