3x^2-3 =5x solve this

Ans:-

3x^2 - 3 = 5x

Now we rearranging this expression ax2 + bx + c = 0 in that manner than we get,

3x^2 - 3 - 5x = 0

∴ 3x^2 - 5x - 3 = 0

Now we solve this sum by quadratic formula,

3x^2-3 =5x solve this

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 .

1+1-12-12-67-972= What is the answer ?

Ans:-

1+1-12-12-67-972 = ?

we solved this problem by golden formula of plus and minus

( +, - ). In this formula -1 -1 = -2,

∴ -3 -3 = -6,

∴ 1 + 1 = 2,

∴ 3 + 3 = 6

∴ 1 + 1 - 12 - 12 - 67 - 972

↓ ↓

2 -1063

∴ 2 - 1063 = 1061

This is our required Ans:- 1061

Find the product of place value and face value of 9 in the year of Independence.

Ans:-

Year of Independence is 1947

so that, the face value of 9 in 1947 is = 9

∴ the place value of 9 in 1947 is = 900

Now the product of place value and face value of 9 in 1947 is = 9 × 900

= 8100

The product of place value and face value of 9 in the year of Independence is = 8100

The ratio of the length of a rectangle to its width is 5:2. If the length of rectangle is 40 cm, what is its width

Ans:

Ratio of length and width of rectangle must be in proportion to the actual length and width of the rectangle.

Let we consider width of rectangle be = x

Given:-

Ratio of Length : Width is = 5 : 2 respectively

Actual Length is = 40 cm

Now we know that, they are in proportion, so we can write them as,

5 : 2 = 40 : x

∴ 5/2 = 40/x

Cross multiplying, we get

5x = 80

x = 16 cm

Therefore width of rectangle is 16 cm.

Expand this expression (p+q²)²

(p + q²)²

We solved this expression by this formula (a + b)² = a² + 2ab + b²

(p + q²)² = p² + 2pq² + q4

so this is our required Ans:- p² + 2pq² + q4

Hope you will find this answer helpful..!!
