3.	Derive shridhar acharya formula by completing square method
Answer» Step-by-step explanation: If we have to solve any quadratic equation, we would probably switch to factorization method. But in some cases, it is not convenient to solve quadratic equations by factorization method. For example, consider the equation x2 + 4x + 2 = 0. In order to solve this equation by factorization method we will have to split the coefficient of the middle term 4 into two integers whose sum is 4 and product is 2. Clearly, this is not POSSIBLE in integers. THEREFORE, we cannot solve this equation by USING factorization method. We can convert any quadratic equation to the form (x + a)2 – b2 = 0 and can easily find its roots. Let us consider the equation 3x2 – 5x + 2 = 0. Here coefficient of x2 is not a perfect square. So, we multiply the equation throughout by 3 to get 9x2 – 15x + 6 = 0 Now we have, 9x2 – 15x + 6 = (3x)2 – 2 x (3x) x 5/2 + 6 = (3x)2 – 2 x (3x) x 5/2 + (5/2)2 – (5/2)2 + 6 = (3x-5/2)2 – 25/4 + 6 = (3x-5/2)2 – ¼ (3x-5/2)2 = ¼ 3x-5/2 = 1/2 or 3x-5/2 = -1/2 3x=1/2+5/2 or 3x=-1/2+5/2 3x=6/2 or 3x = -4/2 x=3/3 or x=-2/3 x=1 or x = -2/3 Here is a formula for finding the roots of any quadratic. It is proved by completing the square. In other WORDS, the quadratic formula completes the square for us. This method is popularly known as Sridharacharya’s formula as it was first given by an ANCIENT Indian mathematics Shridharacharya around 1025 A.D please Mark me as brainlist.

Derive shridhar acharya formula by completing square method

Answer»

Step-by-step explanation:

If we have to solve any quadratic equation, we would probably switch to factorization method. But in some cases, it is not convenient to solve quadratic equations by factorization method.

For example, consider the equation x2 + 4x + 2 = 0. In order to solve this equation by factorization method we will have to split the coefficient of the middle term 4 into two integers whose sum is 4 and product is 2. Clearly, this is not POSSIBLE in integers. THEREFORE, we cannot solve this equation by USING factorization method.

We can convert any quadratic equation to the form (x + a)2 – b2 = 0 and can easily find its roots. Let us consider the equation 3x2 – 5x + 2 = 0. Here coefficient of x2 is not a perfect square. So, we multiply the equation throughout by 3 to get 9x2 – 15x + 6 = 0

Now we have, 9x2 – 15x + 6

= (3x)2 – 2 x (3x) x 5/2 + 6

= (3x)2 – 2 x (3x) x 5/2 + (5/2)2 – (5/2)2 + 6

= (3x-5/2)2 – 25/4 + 6

= (3x-5/2)2 – ¼

(3x-5/2)2 = ¼

3x-5/2 = 1/2 or 3x-5/2 = -1/2

3x=1/2+5/2 or 3x=-1/2+5/2

3x=6/2 or 3x = -4/2

x=3/3 or x=-2/3

x=1 or x = -2/3

Here is a formula for finding the roots of any quadratic. It is proved by completing the square. In other WORDS, the quadratic formula completes the square for us. This method is popularly known as Sridharacharya’s formula as it was first given by an ANCIENT Indian mathematics Shridharacharya around 1025 A.D

Cylinder: d = 1 cm, H = 7 cm Cube: Length of each side a = 7 cm Both of the figures are different in respect of their shapes. Lateral surface of cylinder = 2πrh = 2 × 227 × 72 × 7 = 154 cm2 Lateral surface of the cube = 4l2 = 4 × (7)2 = 4 × 49 = 196 So, cube has the larger lateral surface = 196 cm2.

18.

describe how the two figures at the right are alike and how they are different which box has larger lateral surface area

Answer»

Solution:

The two figures GIVEN are CYLINDER and cube.

Both figures are alike in RESPECT of their same height.

Cylinder: d = 1 cm, H = 7 cm

Cube: Length of each side a = 7 cm

Both of the figures are different in respect of their shapes.

Lateral surface of cylinder = 2πrh

= 2 × 227 × 72 × 7 = 154 cm2

Lateral surface of the cube = 4l2 = 4 × (7)2 = 4 × 49 = 196

So, cube has the larger lateral surface = 196 cm2.
