Question:
If a = 0.1039, then the value of 4a2 – 4a + 1 + 3a is:
[A].0.1039
0.2078
1.1039
2.1039
If a = 0.1039, then the value of 4a2 – 4a + 1 + 3a is:
[A].
[B].
[C].
[D].
Answer: Option C
Explanation:
4a2 – 4a + 1 + 3a
= (1)2 + (2a)2 – 2 x 1 x 2a + 3a
= (1 – 2a)2 + 3a
= (1 – 2a) + 3a
= (1 + a)
= (1 + 0.1039)
= 1.1039
