The quadratic equations:

$3x^2+12x=0\\\\x^2+9x-7=0\\\\x^2-x=8x+2$

The cubic equation: $x^3-4x^2+3=0$

The linear equations:

$x-9=0\\x-2=3x+9$

Expressions for 'c' and 'd' in terms of 'a' will be $(d=4a)$ and $(c=a^2+8)$ .

In question number 12, it's given that $(a+\sqrt{8})^2$ can be written as $(c+d\sqrt{2})$ .

So the expression representing the situation will be,

$(a+\sqrt{8})^2=(c+d\sqrt{2})$

Now simplify the expression,

$a^2+8+2a\sqrt{8}=c+d\sqrt{2}$

$(a^2+8)+2a\sqrt{8}=(c+d\sqrt{2})$

$(a^2+8)+4a\sqrt{2}=(c+d\sqrt{2})$

Compare both the sides of the equation,

$c=a^2+8$

$4a\sqrt{2}=d\sqrt{2}$

$d=4a$

Therefore, $(d=4a)$ and $(c=a^2+8)$ will be the expressions for c and d in terms of a.
