MAT1501 Assignment 1 Multiple choice
Question 1 : Solution
Workings:
2
( a−b )( b−a
2 )
= -1
1
( a−b )( b−a
1 )
= -1
( b−a
a−b )
= -1
( b−a ) = -1(a-b)
( b−a ) = -a + b
b−a=b−a
Therefore A is true
If x = − 1/ 2 and y = −2
4x 3
Then −x 2 - + y2 = 2
y 4
- (1/4) – 4(-1/2)/2 + 4
- (1/4) - -1 + 4
3
- (1/4) + 1 + 4 = 4
4
3
Which is not 2
4
Therefore from answers given (Only A) is correct.
