Determine the real zeros of the polynomial \( q(x) = 2x^4 - 8x^3 + 6x^2 \).

4. Make \( c \) the subject of \( g=\frac{c+3}{4+c}-7 \)

5. Question 5. Solve \( 5 x-3=2 x+6 \)

Add \( 5 \mathrm{a}-3 \mathrm{~b} \) and \( -5 \mathrm{~b}+3 \mathrm{a} \) the result is ...... \[ \begin{array}{l}8 \mathrm{a}-8 \mathrm{~b} \\ 8 \mathrm{a}+8 \mathrm{~b} \\ 8 \mathrm{~b}-8 \mathrm{a} \\ 2 \mathrm{a}-2 \mathrm{~b}\end{array} \]

question 4. Solve \( 3 x+2=2+4 x \)

Three consecutive numbers their sum is 48 write an equation express that is .... \( \begin{array}{l}3 x+2=48 \\ 3 x+4=48 \\ 3 x+3=48 \\ 3 x-3=48\end{array} \)
