2. Find the degree of a polynomial:
a) 2
b) 8
c) 16
d) 24
2a3b5 + 3a2b6c8
3. Find the Sum:
a)3x2 – 2x + 1b) X3 + 2x2 – 2x + 1c)3x2 – 2x + 3d) X3 + 2x2 – 3
(3x – 1 + 2x2) + (x3 – 5x + 2)
4. Find the Difference:
a) x2 – 9x + 6
b) x2 – 9x – 6
c) x2 – x + 6
d) x2 – x – 6
(x2 – 5x) – (4x – 6)
5. The length of a picture is 4 times the width. A picture frame has been added that measures 5 inches thick on each
side. *What is the area of the picture? *The area of the picture and frame? *The area of only the picture frame?
w4w
W + 10
4w + 10
*A = l x wA = 4w(w)A = 4w2
A = l x wA = (4w + 10)(w + 10)A = 4w2 + 40w + 10w + 100A = 4w2 + 50w + 1004w2 + 50w + 100 -
4w2
50w + 100
6. Find the product:
(x – 3)(x – 8)
x2 – 11 x + 24
7. Which expression
represents the area of the rectangle?
8. Simplify:
(x + 8)2
x2 + 16 x + 64
9. Simplify:
-2x2(x2 – 3x + 2)
-2x4 + 6x3 – 4x2
10. Simplify:(3x – 4)(3x + 4)
9x2 – 16
11. Simplify:
(2y + 1)(y2 + 3y – 5)
2y3 + 7y2 – 7y – 5
12. Make sure you can factor X2 + bx + c and ax2 + bx + c as well as
factor the GCF.
GOOD LUCK!!!
