If a = 0.1039, the value of 4a2 - 4a + 1 + 3a is as follows:
A. 0.1039
B. 0.2078
C. 1.1039
D. 2.1039
Answer:C
If a = 0.1039, the value of 4a2 - 4a + 1 + 3a is as follows:
A. 0.1039 B. 0.2078 C. 1.1039 D. 2.1039
Explanation: 1)2 + 4a2 - 4a + 1 + 3a = 4a2 - 4a + 1 + 3a = 4a2 - 4a + 1 + (2a)=2 + 2 x 1 x 2a + 3a = 2 - 2 x 1 x 2a + 3a = 2 - 2 x=2 + 3a = (1 - 2a)2=3a = (1 - 2a)=(1 + a) = 1 + 1 + 1 + 1 + 1 + 1 + 1= (0.1039) =1.1039.
