I have a lot more to do but I really NEED the points. Can you please please please help me?

Answer 1

18x^2+6+4x-15x^2-4+13x
(18-15)x^2 + (4+13)x + (6-4)
3x^2 + 17x + 2


3x^2+6-2x+5x-4x^2+9
(3-4)x^2 + (-2+5)x + (6+9)
-x^2 + 3x + 15


3x^2+3x-7x+3-5x^+2
(3-5)x^2 + (3-7)x + (3+2)
-2x^2 - 4x + 5

-5 is the coefficient of x
-4 is the coefficient of x^2

(m^2-m-4)+(m-5)
m^2 + (-1+1)m + (-4-5)
m^2 - 9

(5x^2+x-3)-(-2x^3+4)
(5- -2)x^2 + (1-0)x + (-3-4)
7x^2 + x - 7

f^2 * f^4 = f^(2+4) = f^6

100^12/100^8 = 100^(12-8) = 100^4

x^16/x^3 = x^(16-3) = x^13

4^4 * 4^6 = 4^(4+6) = 4^10

3^3 * 3^3 = 3^(3+3) = 3^6

Looks like you seriously need to review the pertinent sections of your text.
