Question

x (2x + 3) = x2 + 1 dwighat

समीकरण है या नहीं​

Answer 1

Step-by-step explanation:

yeah it's a equation.... buddy...

$2 {x}^{2} + 3x = 2x + 1$

$= > 2 {x}^{2} + x - 1 = 0$

$= > 2 {x}^{2} + 2x - x - 1 = 0$

$= > 2x(x + 1) - 1(x + 1) = 0$

$= > (2x + 1)(x + 1) = 0$

$= > 2x - 1 = 0 \: \: \: \: \: \: \: or \: \: \: x + 1 = 0$

$= > x = \frac{ - 1}{2} \: \: \: \: \: \: \: \: or \: \: \: x = - 1$

$hence \: \: \: \: x \: = \frac{ - 1}{2} \: \: and \: - 1$
