Answer:

  • The value of x is 45/23.

Given:

  • (2x + 1)² - 4 (x - 3)² = 5x + 10

To find:

  • The value of x.

Solution:

=> (2x + 1)² - 4 (x - 3)² = 5x + 10

=> 4x² + 4x + 1 - 4 (x² - 6x +9) = 5x + 10

=> 4x² + 4x + 1 - 4x² + 24x - 36 = 5x + 10

=> 23x = 45

=> x = 45/23

Therefore, the value of x is 45/23.

Extra information:

  • (a - b)² = (a + b)² - 4ab

  • (a + b)² = (a - b)² + 4ab

  • (a + b)² + (a - b)² = 2 (a² + b²)

  • (a + b)² - (a - b)² = 4ab

AnswEr :-

• Value of x is 45/23.

Given :-

• (2x + 1)² - 4 (x - 3)² = 5x + 10

To Find :-

• Value of x

Solution :-

» (2x + 1)² - 4 (x - 3)² = 5x + 10

→ (2x)² + 2.2x.1 + (1)² - 4 { (x)² + (3)² - 2.x.3 = 5x + 10

→ 4x² + 4x + 1 - 4 { x² + 9 - 6x } = 5x + 10

→ 4x² + 4x + 1 - 4x² - 36 + 24x = 5x + 10

→ 4x + 1 - 36 + 24x = 5x + 10

→ 28x - 35 = 5x + 10

→ 28x - 5x = 10 + 35

→ 23x = 45

x = 45/23

Hence, the value of x is 45/23.
