Answer 13

*tears at hair* i hate algebra.. *cries*

Answer 14

To find non-real solutions -- factor.

a^3 - b^3 = (a - b)(a^2 + ab + b^2)

x^3 - 64 = x^3 - 4^3

Using the pattern, x = a and 4 = b.

(x - 4)(x^2 + 4x + 4^2) = 0
(x - 4)(x^2 + 4x + 16) = 0

Set both parentheses equal to 0.

x - 4 = 0
x = 4 (that's the real solution)

x^2 + 4x + 16 = 0

More factoring will get you nowhere here. It's best to use the quadractic equation.

[-b +or- (root)(b^2 - 4ac)] / 2a

[-4 +or- (root)(4^2 - 4*1*16)] / 2*1
[-4 +or- (root)(16 - 64)] / 2
[-4 +or- (root)(-48)] / 2
Take out i.
[-4 +or- i (root)(48)] / 2
Factor 48 (to see what you can take out of the square root).
[-4 +or- i (root)(2*2*2*2*3)] / 2
[-4 +or- 4i (root)(3)] / 2
Reduce.

-2 +or- 2i (root)(3)

so, either c or d--becuase those options are the same on your question (:

Answer 15

wow thats amazing! i think there are more to them hold on.

Answer 16

no C is 2i3 not B. so would it be B or D?

Answer 17

well your c and d look like this (same)

C. 4,-2+2isqrt3
D. 4,-2+2isqrt3

Answer 18

the ending of B is 1 + 2i sqrt of 3
the ending of D is 2+ 2i sqrt of 3

Answer 19

c or d not b (:

Answer 20

A. 4,-1+2isqrt3
B. 4,1+2isqrt3
C. 4,-2+2i3
D. 4,-2+2isqrt3
these are the right answers. i messed up

Answer 21

D

Answer 22

so B is 4,1+2isqrt3,1 + 2i sqrt of 3
and D is 4,-2+2isqrt3 2+ 2i sqrt of 3

Answer 23

ok thanks a bunch!

Answer 24

yep. anytime :D

Answer 25

i have some more if your up to it?

Answer 26

I could try, sure

Answer 27

Which is a factored form of 8x^3+27?
A(2x+3)(2x+3)(2x+3)
B(2x+3)(4x^2-6x+9)
C(2x-3)(4x^2+6x+9)
D(2x-9)(4x^2+18x+81)

Answer 28

ok thanks

Answer 29

i think C but im not sure

Answer 30

a^3 - b^3 = (a - b) * (a² + ab + b²)

a = 2x and b = -3

<=>

(2x)^3 - (-3)^3 = (2x - (-3)) * ((2x)² + (2x * (-3)) + (-3)²) =

(2x + 3) * (4x² - 6x + 9)

so B

Answer 31

B cool. your a lifesaver!

Answer 32

you know what? I think your right. C is the correct answer. sorry

Answer 33

oh it is? ok i have another one.

Answer 34

(2x)^3 - (3)^3 = (2x - 3)[(2x)^2 + (2x)(3) + (3)^2]
= (2x - 3) (4x^2 + 6x + 9)

Answer 35
