Question

Pls factorise it .....


x⁴ - 3x - 2

Answer 1

$hii.. \\ \\ you \: can \: write \: this \: eqn. \: as : \\ = > {x}^{4} + {x}^{3} - {x}^{3} + 2 {x}^{2} - 2 {x}^{2} - 3x - 2 \\ = > {x}^{4} + {x}^{3} + 2 {x}^{2} - {x}^{3} - {x}^{2} - 2x - {x}^{2} - x - 2 \\ = > ( {x}^{4} + {x}^{3} + 2 {x}^{2} ) + ( - {x}^{3} - {x}^{2} - 2x) + ( - {x}^{2} - x - 2) \\ = > {x}^{2} ( {x}^{2} + x + 2) - x( {x}^{2} + x + 2) - 1( {x}^{2} + x + 2) \\ = > ( {x}^{2} + x + 2)( {x}^{2} - x - 1) \: ans. \\ \\ hope \: this \: helps : )$

Answer 2

Hey guys here is your answer!!!!☺️

$fatorise$


x⁴ - 3x - 2

x⁴ + x² - x² - 3x - 2

x⁴ + x² - (x² + 3x + 2)

x⁴ + x² - (x² + 2x + x + 2)

x⁴ + x² -｛ x(x + 2) + 1(x + 2) ｝

x⁴ + x² - (x + 2) (x + 1)

x⁴ + (x + 2) x² - (x + 1) x² - (x + 2)(x + 1)

x² (x² + x + 2) - (x + 1)(x² + x + 2)

(x² - x - 1)(x² + x + 2)


I HOPE IT WILL HELP YOU ☺️✌️

Thank you ✌️
