1- Leave the 1st case empty

2- Write on the 1st row each element of the trinomial in each case

3-Write on the 1st column in each case each of the element of the binomial

║ y² -3y 9
----------- ║-----------------------------------------------------
y ║    y³ -3y²    9y
----------- ║---------------------------------------------------
3 ║    3y²    -9y    27
------------║----------------------------------------------------
   TOTAL║(y³+3y²) +(-3y²-9y) + ( 9y+27)

If you add the Total you will get: (A) Y³+27

Write the equation of the sphere in standard form. x^2 + y^2 + z^2 + 2x − 4y − 6z = 22

madam [21]

The equation $x^{2} +y^{2} +z^{2} +2x-4y-6z=22$ in standard form looks like $(x+1)^{2} +(y-2)^{2} +(z-3)^{2} =(6)^{2}$ .

Given equation of sphere be $x^{2} +y^{2} +z^{2} +2x-4y-6z=22$ .

We are required to express the given equation in the standard form of the equation of sphere.

Equation is basically relationship between two or more variables that are expressed in equal to form. Equation of two variables look like ax+by=c. It may be linear equation,quadratic equation, cubic equation or many more depending on the powers of variables. The standard form of the equation of sphere looks like $x^{2} +y^{2} +z^{2} =r^{2}$ .
