Question

(x +2)² = 2x² खालीलपैकी कोणते समीकरण वर्गसमीकरण आहे?​

Answer 1

Answer:

$\huge x = 2$

Step-by-step explanation:

${(x + 2)}^{2} = 2 {x}^{2}$

By using the algebraic identity: (a+b)² = a² + 2ab + b², we get:

$= > {x}^{2} + (2 \times x \times 2) + {2}^{2} = 2 {x}^{2}$

$= > {x}^{2} + 4x + 4 = 2 {x}^{2}$

$= > 2 {x}^{2} - {x}^{2} = 4x + 4$

$= > {x}^{2} - 4x + 4 = 0$

$= > {(x)}^{2} - (2 \times x \times 2) + {(2)}^{2} = 0$

$= > {(x - 2)}^{2} = 0$

$= > x - 2 = 0$

$= > x = 2$
