Question

Tell me if im right or wrong pleaseee????

Which is the completely factored form of x6 64y3?
(Points : 4)
(x^2- 4y)(x^4 + 4x^2y + 16y^2)

(x^2 + 4y)(x^4- 4x^2y + 16y^2)

(x^2 -4y)(x^4 -16y^2)

(x^2 - 4y)^3
I think its B

Answer 1

Which function is an even function?
(Points : 4)
f(x) = -x^2

f(x) = 6x^3

f(x) = -x- 2

f(x) = 2x^3 + 2
I think its B

Answer 2

Which represents x2 - 7x - 60 in factored form?
(Points : 4)
(x -5)(x + 12)

(x - 6)(x + 10)

(x + 5)(x -12)

(x - 5)(x - 12)
I think the answer is C or D but im not sure???

Answer 3

Which represents x^2 -12x + 36 in factored form?
(Points : 4)
(x + 6)(x -6)

(x - 6)^2

(x + 6)^2

(x - 4)(x - 9)
I think its B

Answer 4

for 1st question use formula

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

\(\Large x^6-64y^3=(x^2)^3-(8y)^3\)

Answer 5

btw
in ur question the sign is missing between

Which is the completely factored form of x6 \( \Large (?)\) 64y3?"

Answer 6

a function is \(\large even\) function when

\(\Large f(x)=f(-x)\)

a function is \(\large odd\) function when

\(\Large f(x)=-f(x)\)

Answer 7

\(\Large f(x) = 6x^3\)


\(\Large f(-x) = 6(-x)^3=-6x^3\)

\(\Large \text{so ur option B is not correct here}\)
\

Answer 8

\(\Large f(x) = -x^2\)

\(\Large f(-x) = -(-x)^2=-x^2\)

so option \(\Large A\) is correct

Answer 9

What about the other ones?

Answer 10

\(3.\)
\(\Large x^2 - 7x- 60\) can be written as
\(\Large x^2 - 12x+5x- 60\) now factor it

Answer 11

x^2 -7x -60

Answer 12

last one is \(\Huge \checkmark\)

Answer 13

I have 3 more can you check those @mathmath333

Answer 14

Which is equal to (4x - 1)(3x + 2)?
(Points : 4)
12x^2 - 5x + 2

12x^2 + 5x - 2

7x^2 + 5x - 2

12x^2 - 2
I think its A

Answer 15

Which is equal to (2x^2 - 5x + 4) (4x^2 + 3x - 2)?
(Points : 4)
2x^2- 8x + 6

6x^2 - 2x + 2

2x^2- 2x + 2

2x^4 - 8x^2 + 6
I think its C

Answer 16

Which represents the polynomial in standard form?

12x^2 - 9x^3 + 5x^2 - 6x^3 + 3 + 2x

(Points : 4)
17x^2 - 15x^3 + 2x + 3

4x^11 + 3

-3x^3 + 17x^2 + 2x + 3

-15x^3 + 17x^2 + 2x + 3
I think its D

Answer 17

@mathmath333 could you please check these?

Answer 18

@FireWolfSpirit can you check them ?

Answer 19

\(\Large (4x - 1)(3x + 2)\)

its not option \(\Large A\) try again

Answer 20

i think the question is in correct here


Which is equal to (2x^2 - 5x + 4) (4x^2 + 3x - 2)?

Answer 21

or the options

Answer 22

Which represents the polynomial in standard form?

12x^2 - 9x^3 + 5x^2 - 6x^3 + 3 + 2x

option \(\Large D\) is correct here
