STEP-BY-STEP SOLUTION:

= a^3 - 4a^2 + 12 - 3a

= a^2 ( a - 4 ) + 3 ( 4 - a )

= a^2 ( a - 4 ) - 3 ( a - 4 )

= ( a - 4 ) ( a^2 - 3 )

a^3-4a^2+12-3a=(a^3-4a^2)-(3a-12)\\\\=a^2(a-4)-3(a-4)=\boxed{(a-4)(a^2-3)}\\\\=(a-4)(a^2-(\sqrt3)^2)\\\\\text{use}\ a^2-b^2=(a-b)(a+b)\\\\=\boxed{(a-4)(a-\sqrt3)(a+\sqrt3)}

Distance formula

\boxed{\sf \sqrt{(x_2-x_1)^2+(y_2-y_1)^2}}

Now

#1

\\ \tt\Rrightarrow AB=\sqrt{(3-3)^2+(-2-8)^2}=\sqrt{100}=10units

#2

\\ \tt\Rrightarrow OK=\sqrt{(5-7)^2+(-2+2)^2}=\sqrt{4}=2units

#3

\\ \tt\Rrightarrow LM=\sqrt{(-4-4)^2+(6+4)^2}=\sqrt{64+100}=\sqrt{164}\approx 13units

#4

\\ \tt\Rrightarrow PC=\sqrt{(5-2)^2+(1-3)^2}=\sqrt{9+4}=\sqrt{13}=3.2units

#5

\\ \tt\Rrightarrow QR=\sqrt{(-2+10)^2+(3-9)^2}=\sqrt{64+36}=\sqrt{100}=10units
