300

Write as one log:

log₂(3)+2log₂(x)

(Write on board) 

Expand: log Squareroot of x divided by y to the 5th 

1/2 log(x)-5log(y)

Factor: (x²-16)

(x+4)(x-4)

200

Divide:

(x²-2x-15)/(x+3)

(x-5)

300

If the roots of a polynomial are -2, and 3, what are the factors

(x+2)(x-3)

400

Factor Completely:

x⁴-x²-12

(x+2)(x-2)(x²+3)

500

Is x-2 a factor of x³+x²-34x=56? Why or Why not?

No, because the remainder is -112.
