Hello friends my name is Rajakumar Dayashankar Gupta . Here I am started to write blog on name scientechplus . I am started to writing this blog post on science , technology and engineering since 2020 . I completing my ssc , than after I go for stream in science field , than after completing my 12th science than later I realize my self , I am interested in electronics fields , so I start learning in diploma electronics engineering . My journey is quite interesting to choosing right decision of my aim . And I want to explain the concept in simple and precise way . I every time want to learn something new , it means that something new from open minded from our environment . To learn something new from our expectation . It quite special and very interested to hear that , when we imagine or think we go to learn something very uniqueness our eyes fill with glow , that moment is such a very great pleasurable moment we feel isn't it ? . And I want to share the information , facts , knowledge related to all science , technology and engineering in detail , simple and precise way .

The degree of x2 – 5x + 2 = x3 is:

x2 – 5x + 2 = x3

x2 - 5x + 2 - x3 = 0

-x3 + x2 - 5x + 2 = 0

If we change the sign of these equation then,

x3 - x2 + 5x - 2 = 0

Ans:- 3

Note: The degree is the value of greatest exponent of any expression.

Find A: C, if A:B = 7:8 and B:C = 16:21

Solution:-

A:B = 7:8 is written as A/B = 7/8

B:C = 16:21 is written as B/C = 16/21

We have to find A:C = ?

A:C is written as A/C

A/C = A/B × B/C

A/C = 7/8 × 16/21

A/C = 2/3

A:C = 2:3

Ans:- A:C = 2:3

Add the following terms -2mm, 4 mn, - 6 mn

= mn - 2mm + 4mn - 6mn

= -2mm + mn (1 + 4 - 6)

= -2mm + mn (-1)

= -2mm - mn

Ans:- -2mm - mn
