Question

(x−4)(2x+3)=2x to the power of 2
can any one solve this problem ​

Answer 1

Step-by-step explanation:

Given:

› (x - 4)(2x + 3) = 2x²

To find:

› Value of x.

Solution:

› (x - 4)(2x + 3) = 2x²

=> x(2x + 3) -4(2x + 3) = 2x²

=> 2x² + 3x - 8x - 12 = 2x²

=> 2x² - 5x - 12 = 2x²

=> 2x² - 2x² - 5x - 12

=> -5x - 12 = 0

=> -5x = 12

⇒ x = 12/-5

=> x = -12/5

∴ x = -2 ⅖

Answer 2

Step-by-step explanation:

Given:

› (x - 4)(2x + 3) = 2x²

To find:

› Value of x.

Solution:

› (x - 4)(2x + 3) = 2x²

=> x(2x + 3) -4(2x + 3) = 2x²

=> 2x² + 3x - 8x - 12 = 2x²

=> 2x² - 5x - 12 = 2x²

=> 2x² - 2x² - 5x - 12

=> -5x - 12 = 0

=> -5x = 12

⇒ x = 12/-5

=> x = -12/5

∴ x = -2 ⅖
