Question

Q4:
The value of (X + 0.1) (X -0.1) is
1. O (X*-0.1)
2. O (X2-0.01)
3. O (X2-1)
4. O None of these​

Answer 1

Answer is B

Step-by-step explanation:

(x+0.1) (x-0.1)

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

where a = x , b = 0.1

${(x)}^{2} - {(0.1)}^{2} = {x}^{2} - 0.1$

therefore answer is option B
