Nonlinear Systems of Equations
zheka24 [161]

The square root and cube root identities are proved.

According to the statement

we have to find that the use of the square root identity (x − y)2 = x2 − 2xy + y2

And use of cube root identity a3 + b3 = (a + b)(a2 − ab + b2).

So, For this purpose, we know that the

A. Let us assume the two conditions.

So,

2x + 3y = 6  -(1)

4x + 7y = 8  -(2)

Here we use elimination method

So, Multiply 4 with (1) and 2 with (2)

8x + 12y = 24  

8x + 14y = 16  

Now eliminate x from these equations

-2y = 8

here y is -4.

and the x become

2x + 3y = 6  

2x -12 = 6

2x = 18

x = 9.

B. For the use of identity (x- y)^{2}  = x^{2} - 2xy + y^{2}

Let us assume a number 26 and 28 then fill it in the condition then

(28- 26)^{2}  = 28^{2} - 2(28)(26) + 26^{2}

Then

(28- 26)^{2}  = 784 - 1456 + 676

(28- 26)^{2}  = 4

And we have to prove the cube root identity then

The identity is

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

Then let us assume the number 8 and 9 then

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

8^{3}  + 9^{3}  = (8 + 9)(8^{2} - 8*9 + 9^{2})

8^{3}  + 9^{3}  = (17)(64 - 72 + 81)

8^{3}  + 9^{3}  = (17)(73)

8^{3}  + 9^{3}  = (1241)

Hence by this way we prove the square and cube root identities.

So, The square root and cube root identities are proved.
