For this question, we can use ratios of similar triangles to solve for our side QR.

$\frac{AB}{QR} = \frac{AC}{QS}$

$\frac{50}{QR} = \frac{60}{6}$

10QR = 50

QR = 5 cm

Simplify Completely:

raketka [301]

$5 \sqrt{162}-3 \sqrt{18}-4 \sqrt{98}= \\ 5\cdot 9 \sqrt{2}-3\cdot 3 \sqrt{2} -4\cdot 7\sqrt{2}=\\ 45 \sqrt{2}-9 \sqrt{2} -28\sqrt{2}=\\ 8 \sqrt{2}$

You want to make sure to factor each equation as much as you can first.
So just focus on the numerator first. $x^3-6x^2+8x$
To factor the numerator:
$(x)(x^2-6x+8)$ factor out an x
$(x)(x-4)(x-2)$ factor out the rest completely.

Now for the denominator: $-4x^2+4x+24$
$(-4)(x^2+x+6)$ factor out a -4
$(-4)(x+3)(x-2)$ factor out the rest.

This leaves you with:
$\frac{(x)(x-4)(x-2)}{(-4)(x+3)(x-2)}$

Then you can simplify:
$\frac{(x)(x-4)}{(-4)(x+3)}$

I'm not sure what you're supposed to find exactly, so if you need more help you can ask me (:
