Hello everyone i need ur help to factor out this in a easy way.

Answer:

  (x -1/4)(x -1)(x +1)

Step-by-step explanation:

Pairs of coefficients have the same ratio, so it is likely that you can factor this by grouping pairs of terms.

  x³ -x -1/4x² +1/4 = (x³ -x) -(1/4x² -1/4) . . . . . . note the signs

  = x(x² -1) -1/4(x² -1)

  = (x -1/4)(x² -1)

The difference of squares (x² -1) is a special form that has factors (x -1)(x +1)

Your factoring is ...

  (x -1/4)(x -1)(x +1)

_____

Additional comment

The difference of squares factors like this:

  a² -b² = (a -b)(a +b)

  (c)  factoring and the zero-product principle

Step-by-step explanation:

Factoring is always an efficient method of solving a quadratic, if it has nice integer factors that can be easily identified. Here, the two prime factors of 35 have a sum of 12, so the factored form is easily found to be ...

  (x +5)(x +7) = 0

This basically shows you the solutions are x=-5 and x=-7 "by inspection" in one step.

By contrast, the quadratic formula has 4 multiplications, a division, a square root, and 3 additions. That's a significant amount of arithmetic to get to the answers.

Factoring is the most efficient way to solve this quadratic.

When 8 is added to the number that is produced by doubling the number x, the result is equal to 8 times the number
that is 5 less than x. What is the value of x? Please help I will give you brainless please

Answers

answer:

x=8

Step-by-step explanation:

8+ (2x) = 8*(x-5)

8*(x-5) applies to the distributive law : a(b-c) = ab-ac

a=8 b=x c=5

8x-8*5

8x-40

then add 8+(2x) back into the equation and you have

8+(2x) = 8x-40

subtract 8

2x=8x-48

subtract 8x

-6x=-48

divide by -6

x=8

check work by plugging it in to the provided info-

8*2 = 16

16+8 = 24

8-5 = 3

3*8=  24

x=8

f(x)=10-9/2x
if f(x)=-53x find x

Answers

Answer:

x = -20/97

Step-by-step explanation:

f(x) = -53x is your output

so -53x = 10-9/2x

-53x - 10 = -9/2x

lets clear the fraction by multiplying each side by 2

-106x - 20 = -9x

-97x = 20

x = -20/97

When f(x) is equal to -53x, the value of x is approximately -0.2062. To find the value of x when f(x) is equal to -53x, we can set the two expressions equal to each other and solve for x:

Given: f(x) = 10 - (9/2)x , And: f(x) = -53x

Setting them equal to each other: 10 - (9/2)x = -53x

To solve for x, let's first get rid of the fraction. We can do this by multiplying the entire equation by 2: 2 * (10 - (9/2)x) = 2 * (-53x)

20 - 9x = -106x

Now, let's isolate the variable x on one side of the equation. Let's move the -9x term to the other side by adding 9x to both sides:

20 - 9x + 9x = -106x + 9x

20 = -97x

Finally, to find x, divide both sides by -97: x = 20 / -97

x ≈ -0.2062 (rounded to 4 decimal places)

So, when f(x) is equal to -53x, the value of x is approximately -0.2062.

Convert 2.5 into Fraction and ¹⁹⁄₂₀ to decimal form

Answers

Answer:

0.25 would be 1/4 and 19/20 would be 0.95

Step-by-step explanation:

you can get 19/10 be divideing

and 0.25 by solving

Let’s start with 2.5 into a fraction.

2.5 has a decimal and a whole number part, so you can know that you will have 2 as your whole number.

.5 is five tenths, so you could say 5/10.

5/10 simplified is 1/2.

2.5 as a fraction is 2 1/2.

19/20 is a little harder, but let’s start!

We need to find what 20 is multiplied by to get 100. 100 divided by 20 is 5.

Now that you have that number, you want to multiply both the numerator and the denominator by 5.

19 x 5 = 95
_____
20 x 5 = 100

95/100 is easy to turn into a decimal.
