Answer:

ii. yes. suppose a is negative, so write a = -b where b is positive. let c be a

positive number such that c" = b. then (-c)" = a because (-1)" = -1 since

n is odd.

3. x negative, y positive 4. x negative, y negative

ii, §3, p. 33

5. y = -~x + i 6. y = -ix + s 7. x = j2

24. y=(x-j2)c~-~)+2 25. y= -(x+ l)(j23+ 1)+2

26. y = (x + 1)(3 + j2) + j2 29. (a) x = -4, y = -7 (b) x = ~, y = i

(c) x = -!, y = 1 (d) x = - 6, y = - 5

5. (x - 2)2 + (y + 1)2 = 25 6. x 2 + (y - 1)2 = 9 7. (x + \)2 + y2 = 3

8. y + ¥ = 2(x + w 9. y - 1 = (x + 2)2 10. y + 4 = (x - \)2

ii. (x + 1)2 + (y - 2)2 = 2 12. (x - 2)2 + (y - \)2 = 2

Answer:

Q is x^2((4x+1) (4x-1)) and P is (2x-1)(x-3) (x+3) + 3(x+3)(4x+1)(4x-1)

Step-by-step explanation:

You can further factor the equations by simplifying certain areas, i.e. taking 3 out of (12x^2-3) to make it factorable, or taking x^2 out of the second one to make it factorable
