Classify the following polynomial: \( 2x^{3} - 4x + 6 \).

2.3 Express \( \frac{1}{\sqrt{2}+1} \) in its simpl

2imalify \( \frac{x^{2}-y^{2}}{x^{2} x y} \) \( \frac{y+2 x-3 y}{3 x-2 y}=4 \), evaluate \( 2 x y \) If \( z=\sqrt{x^{2}-y^{2}} \), express \( x \) interm 9 \( y \) and 2

Question 8 ( 3 marks) What is the equation of the line that passes through the points \( (1,6) \) and \( (3,2) \) ? \( y=\square x+\square \)

\( x = \frac { - ( - 1 ) \pm \sqrt { - 79 } } { 2.1 } \)

\( \therefore \sqrt { x } ( x ^ { \frac { 5 } { 2 } } + x ^ { 2 } + 5 ) \)
