(d) \( 4 r^{2}-7 r+3 \)

5xy-si is 7 - \( 10 \mathrm{si}+3 x y \)

Mathematics/P1 QUESTION 1 \( \begin{array}{ll}1.1 & \text { Solve for } x \text { - Grade } 11 \\ 1.1 .1 & x^{2}+5 x-6=0 \\ 1.1 .2 & 5 x^{2}+2 x-6=0 \text { (correct to TWO) decimal places) } \\ 1.1 .3 & (2 x+3)(3-x)>4 \\ 1.1 .4 & \sqrt{x+2}+x=4\end{array} \)

Factorise the following polynomial express theorem: \( f(x)=x^{3}-2 x^{2}-5 x+6 \)

Expand and simplify \( x(2 x-4)+x(5 x+8) \)

If a line goes up from left to right, what can you say about its slope? Give an example.
