Answer:

(x - 2)(x² + 2x + 4)

Step-by-step explanation:

A difference of cubes factors in general as

• a³ - b³ = (a - b)(a² + ab + b² )

note 8 = 2³ = 8 ⇒ b = 2 , with a = x

Hence

x³ - 8

= x³ - 2³

= (x - 2)(x² + 2x + 2²) = (x - 2)(x² + 2x + 4)

Answer: The rewritten expression would be (x-2)(x^2+2x+4)

Step-by-step explanation:

Since we have given that

x^3-8

We need to use the difference of cubes:

As we know the formula of "Difference of cubes":

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

So, it can be written as

(x)^3-(2)^3=(x-2)(x^2+2x+4)

Hence, the rewritten expression would be (x-2)(x^2+2x+4)

Two less than three times a number is the same as six more than twice the number. Write an equation and solve to find the number
lapo4ka [179]

Answer: 8

Step-by-step explanation:

Let the number be represented by x.

Two less than three times a number is the same as six more than twice the number. This will be:

(3 × x) - 2 = (2 × x) + 6

3x - 2 = 2x + 6

Collect like terms.

3x - 2x = 6 + 2

x = 8.

The number is 8
