To do these types of problems fast, I highly recommend you learn synthetic division-it helped me so much in Algebra II class.
It is kind of hard to explain on here, so I recommend searching synthetic division on you tube.
Anyway, by doing that you get (x-5) as a zero and are left with 6x^2 -x -1, which you can plug in the quadratic formula, and you get x= -1/3 and x=1/2

Hope, this tip helps you get started, but if not another tip would be (although it takes much more time) to just start dividing the polynomial by numbers like: x= (+/-) 6,1,2,3,5 because these numbers are factors of 5 or 6.

Find m∠USW if m∠USW = 7x - 34 and m∠TSR = 4x + 9.
nikitadnepr [17]

In this question, it is given that the measurement of angles USW and TSR are 7x-34 and 4x+9 .

First we have to find the relationship between those two angles .

And these angles are vertical opposite angles which are congruent .

Therefore

m \angle USW = m \angle TSR

7x-34 = 4x+9
\\
3x = 43
\\
x = 14.33

Therefore measurement of angle USW is

=7(14.33)-34 =66.31 degree
