Answer:

(b+x)(−b+x)(b−2)

Step-by-step explanation:

Factor bx2 + 2b2 − b3 − 2x2 − b3 + bx2 + 2b2 − 2x2 = (b+x)(−b+x)(b−2)

adam wants to compare the fractions 3/12,1/6, and 1/3.he wants to order them from least to greatest and rewrite them so they all

Digiron [165]

3/12 ; 1/6 ; 1/3

Adam must first get the least common multiple of each denominator.

12 : 12, 24, 36
6 : 6, 12, 18
3 : 3, 6, 9, 12

12 is the least common denominator.

We, then, multiply each denominator by a number that will produce 12.

12 x 1 = 12
6 x 2 = 12
3 x 4 = 12

Each number multiplied to the denominator must be the number used to multiply each numerator.

3/12 * 1/1 = 3/12
1/6 * 2/2 = 2/12
1/3 * 4/4 = 4/12

Since they now share a common denominator, the numerator will become the basis of the fraction's value. The greater the numerator, the greater the fraction's value.

Fractions in order from least to greatest = 2/12 ; 3/12 ; 4/12

Substitute each fraction with its original fraction:
2/12 ⇒ 1/6 : least
3/12 ⇒ 3/12 : middle
4/12 ⇒ 1/3 : greatest

Find the smallest possible solution to 2/3x^2=24

Bezzdna [24]

$\dfrac{2}{3} x^2 = 24$

---------------------------------------------------------------------
Divide by 2/3 on both sides :
---------------------------------------------------------------------
$x^2 = 24 \div \dfrac{2}{3}$

---------------------------------------------------------------------
Change the divide fraction to multiplication fraction :
---------------------------------------------------------------------
$x^2 = 24 \times \dfrac{3}{2}$

---------------------------------------------------------------------
Simplify :
---------------------------------------------------------------------
$x^2 = 36$

---------------------------------------------------------------------
Square root both sides :
---------------------------------------------------------------------
$x = \pm \sqrt{36}$

---------------------------------------------------------------------
Answer :
---------------------------------------------------------------------
$x = \pm6$

---------------------------------------------------------------------
Answer: The smallest possible value of x is -6
---------------------------------------------------------------------
