Answer 2

Question :--- x²+3x + 9/4 का गुणनखण्ड ?

हमे पता है कि (x²+2xy+y²) = (x+y)² होता है ll

इसलिए ,

${x}^{2} + 2xy + {y}^{2} = {x}^{2} + 3x + \frac{9}{4} \\ \\ 2xy = 3x \\ \\ y = \frac{3}{2} \\ x = x \\ \\ \\ so \\ \\ {x }^{2} + 3x + \frac{9}{4} = {(x)}^{2} + 2 \times x \times \frac{3}{2} + {( \frac{3}{2} )}^{2} \\ \\ \\ or \\ \\ {x }^{2} + 3x + \frac{9}{4} = \: (x + \frac{3}{2} )^{2} (ans)$

[1] ( a + b )² = a² + 2ab + b²

[2] ( a – b )² = a² – 2ab + b²

[3] ( a + b )³ = a³ + 3a² b + 3ab² + b³

[4] ( a – b )³ = a ³ – 3a² b + 3ab² – b³

[5] ( a + b )( a ² - ab + b² ) = a³ + b³

[6] ( a – b )( a ² + ab + b² ) = a³ – b³
