1 answer:
andrew11 [14]3 years ago
8 0

Answer:

a. 0

b. 0 (undefined)

c. 14

d. 0 (undefined)

Step-by-step explanation:

a. Make x on its own

x = 5 - 5

x = 0

b. Collect like terms (terms that have same variable)

2x - 6 = 2x - 6

Rearrange equation

2x - 2x = -6 + 6

0x = 0

x = 0 (undefined) -- This is because when you divide something by 0 (when 0 is the denominator), it is undefined

c. Rearrange to make whole numbers on one side

3x = 43 - 1

3x = 42

Divide both sides by 3 to make x on its own

x = 14

d. 4x - 4x = 7 + 1

0x = 8

x = 0 (undefined)

What are the roots of the polynomial equation x3-7x=6x-12?
Ilia_Sergeevich [38]
This is not a polynomial equation unless one of those is squared.  As it stands x=-.833.  If you can tell me which is squared I can help solve the polynomial.

Ok, that is usually notated as x^3 to be clear.   I'll solve it now.

x^3-13x-12=0

Then use factor theorum to solve x^3-13x-12/x+1 =0
So you get one solution of x+1=0
x=-1

Then you have x^2-x-12 now you complete the square.

Take half of the x-term coefficient and square it. Add this value to both sides. In this example we have:

The x-term coefficient = −1

The half of the x-term coefficient = −1/2

After squaring we have (−1/2)2=1/4

When we add 1/4 to both sides we have:

x2−x+1/4=12+1/4

STEP 3: Simplify right side

x2−x+1/4=49/4

STEP 4: Write the perfect square on the left.

<span>(x−1/2)2=<span>49/4
</span></span>

STEP 5: Take the square root of both sides.

x−1/2=±√49/4

STEP 6: Solve for x.

<span>x=1/2±</span>√49/4

that is,

<span>x1=−3</span>

<span>x2=4</span>

<span>and the one from before </span>

<span>x=-1</span>
