BMT1014 TUTORIAL 1 1. Determine whether each of the following statement is either TRUE or FALSE. a) b) c) d) 0/0 is a rational number. -3 is to the right of -4 on the real-number line. The negative of 7 is -1/7. x − y = −y + x 2. Perform the indicated operation and simplify: a) (4a 2 − 2ab + 3) + (5c − 3ab + 7 ) b) k 3(k + 2 )(k − 4 ) + 53k (k − 7 ) (2 x + 3 y )2 c) (2x + 3 y )2 − (2 y + 1)(3x − 2) + 2(x − y ) d) 3 2 + 2 x − x−6 x + x−2 e) 2 2 ( x + 1) 5 − (2 x + 6) 2 4 f) ( 2 x + 1) − ( 3x − 2 ) g) 10 x 3 5x 2 x −1 x +1 h) 2 +2 x+2 8 x− x 2 2 + 5x ( 2 − x )
