Step-by-step explanation:

STEP1:Equation at the end of step 1

(((2 • (x3)) + 32x2) - 6x) - 40

STEP 2 :

Equation at the end of step2:

((2x3 + 32x2) - 6x) - 40

STEP3:Checking for a perfect cube

3.1 2x3+9x2-6x-40 is not a perfect cube

Trying to factor by pulling out :

3.2 Factoring: 2x3+9x2-6x-40

Thoughtfully split the expression at hand into groups, each group having two terms :

Group 1: -6x-40

Group 2: 2x3+9x2

Pull out from each group separately :

Group 1: (3x+20) • (-2)

Group 2: (2x+9) • (x2)

Write the algebraic expression for the difference between the squares of two numbers.

V125BC [204]

The algebraic expression for the difference between the squares of the two numbers, supposing the two numbers to be a and b, is

a² - b² = (a + b)(a - b).

An algebraic expression is a combination of terms, where the terms are separated using mathematical operators like plus (+), minus (-), multiply (*), and divide (/).

The terms are combinations of numerals and variables.

Variables are represented alphanumerically, which can hold any value as per the expression they are used in.

In the question, we are asked to write the algebraic expression for the difference between the squares of two numbers.

We assume the two numbers to be a and b respectively.

Thus, we are asked to write an expression for the difference between the square of a and square of b, that is, we are asked to write an expression for a² - b².

We know that a² - b² is an identity, which can be shown as (a + b)(a - b).

Thus, the algebraic expression for the difference between the squares of the two numbers, supposing the two numbers to be a and b, is a² - b² = (a + b)(a - b).
