Factorise fully x^3-x

Mathematics
1 answer:
MA_775_DIABLO [31]3 years ago
3 0

Answer:

x(x+1)(x-1)

Step-by-step explanation:

We see that the two terms share an x, so we can pull that out:

x^3-x=x(x^2-1)

Now notice that we have a difference of squares (x^2-1). Given a difference of squares, a^2-b^2, this can always be factored into (a+b)(a-b). We can use this in this case: x^2-1=(x+1)(x-1).

So, our final factorized form is: x(x+1)(x-1).

Hope this helps!

Use the x-intercept method to find all real solutions of the equation. -9x^3-7x^2-96x+36=3x^3+x^2-3x+8
Varvara68 [4.7K]

Answer:

  x ≈ 0.290640965127

Step-by-step explanation:

By subtracting the right side of the equation, we get a function that is zero at a real solution for x. The only x-intercept is at approximately 0.290640965127.

___

The graph shows the x-intercept to be 0.2906. The value above was obtained by Newton's method iteration. The roots of this cubic will all be irrational.

PLZ HELP!!!
dexar [7]

Solution:

The given equation is:

3^2 x + 7^2= 2 ^x\\\\9 x +49 =2^x

A: Taking , x=1

L H S = 9 × 1  + 49 = 9 + 49= 58

R H S : 2^x=2^1=2

L H S ≠   R H S

B: Taking x=3

L H S = 9 × 3 + 49=27 + 49=76

R HS = 2^x = 2^3 = 8

L H S ≠  R H S

C: Taking x=5

L H S = 9 × 5 + 49

        = 45 + 49

       = 94

R H S:

2^x=2^5=32

L H S ≠ R H S

(D)

when , x= 8

L H S

9 × 8 + 49

= 72 + 49

= 121

R HS:

2^x=2^8 =256

L H S ≠ R H S

Mark as brainleist if right? HMMMMMMMM<br> FELLING GOOD TODAY
Alekssandra [29.7K]

Answer:

-50

Step-by-step explanation:

Add 2 to both sides: \frac{c}{5} =-12+2=-10

Multiply both sides by 5: c = 5 * (-10) = -50.

Thus, the answer is -50.

Hope this helps!

If a canoe travels with a speed of A mph for 3 hours, and then with a speed of B mph for the rest of the journey, how long does
mylen [45]
For time-speed-distance problems, you use the relationship
.. speed = distance/time
in any of its various forms.

The distance traveled at A mph is
.. distance = speed * time
.. distance = A*3

The time required for the rest of the journey is
.. time = distance / speed
.. time = (C -3A)/B

The the total time required to travel C miles is the 3 hours for the first part plus the time for the rest of the journey.
.. total journey time = 3 + (C -3A)B . . . . . hours
