3/a + 1/2 -> ((3*2) + (1*a)) / (a*2) -> (6 + a)/2a

so

(6 + a)/2a = 11/5a -> (6 + a)*5a/2a = 11 -> 6 + a = 11*2/5

so

a = 22/5 - 6 = 4.4 - 6 = -1.6

so

(6 + a)/2a = 11/5a -> (6 + a)*5a/2a = 11 -> 6 + a = 11*2/5

so

a = 22/5 - 6 = 4.4 - 6 = -1.6

Let a and b be the numbers

Sum is 205 :** a+b=205**

Difference is 75:**a-b=75**

add the two sides on the left of the = signs a+b+a-b=2a

add the two sides on the right of the = signs 205+75=280

Equate 2a and 280

2a=280

**a=140**

Substitute 140 for a in one of the two original equations. Take for example the first

140+b=205

b=205-140=65

Check 140+65=205 OK

**a=140, b=65**

Sum is 205 :

Difference is 75:

add the two sides on the left of the = signs a+b+a-b=2a

add the two sides on the right of the = signs 205+75=280

I believe that the algebraic expression should be written as:

(a + 2b)(a^2 - 2ab - 4b^2)

which can be rewritten as:

(a + 2b)^2 * (a - 2b)

The simplified form of this expression is:

(a^3 - 2a^2b - 4ab^2 + 2a^2b - 4ab^2 - 8b^3)

which can then be further simplified as:

(a^3 - 8b^3)

(a + 2b)(a^2 - 2ab - 4b^2)

which can be rewritten as:

(a + 2b)^2 * (a - 2b)

The simplified form of this expression is:

(a^3 - 2a^2b - 4ab^2 + 2a^2b - 4ab^2 - 8b^3)

which can then be further simplified as:

(a^3 - 8b^3)

Here, We deal with Some Special Products in Polynomials.

Certain products of Polynomials occur more often

in Algebra. They are to be considered specially.

These are to be remembered as Formulas in Algebra.

Remembering these formulas in Algebra is as important

as remembering multiplication tables in Arithmetic.

We give a list of these Formulas and Apply

them to solve a Number of problems.

We give Links to other Formulas in Algebra.

Here is the list of Formulas in

Polynomials which are very useful in Algebra.

Formulas in Polynomials :

** Algebra Formula 1 in Polynomials: ** * Square of Sum of Two Terms: *

** (a + b)2 = a2 + 2ab + b2 **

** (a - b)2 = a2 - 2ab + b2 **

** (a + b)(a - b) = a2 - b2 **

** (a + b)(a2 - ab + b2) = a3 + b3 **

** (a - b)3 = a3 - 3a2b + 3ab2 - b3 = a3 - 3ab(a - b) - b3 **

(First term + Second term)2

= (First term)2 + 2(First term)(Second term) + (Second term)2

this is a simple algebraic equation in which we have to calculate the value of 'x' using simple operations

7+(9-5x)=5(2-x)

step 1(pen the brackets) 7+9-5x=10-5x

step 2(add 7 and 9) 16-5x=10-5x

now as 5x gets cancelled both the sides of the equal sign therefore no solution of this algebraic equation exist.

7+(9-5x)=5(2-x)

Hello

**Rectangular Prism/Cuboid Definition:**

A Rectangular Prism/Cuboid is a solid figure bounded by six rectangular faces, a rectangular box. All angles are right angles, and opposite faces of a cuboid are equal. It is also a right rectangular prism.

**Rectangular Prism/Cuboid Formula**:

Area of Base(A) = l * w

Perimeter of Base(P) = 2l + 2w

Surface Area of Prism = 2(lw) + (2l + 2w)h = 2A + Ph

Volume of Prism = lwh = Ah

Diagonal of Prism = Sqrt(l² + w² + h²)

where

l = length, w = width, h = height

Hope this helps, if so do rate the solution

what about it? It's not really a problem... there is no = and no indication of which variable you are solving for.

in A-(B-2A)

You can simplify to 4A - B

But it cannot be SOLVED.
