if say correct answer I will mark u as brainlist answer​

Answer 1

Answer:

${ ({x}^{2} - x + 1)}^{4} - 6 {x}^{2} {( {x}^{2} - x + 1 )}^{2} + 5 {x}^{2} = 0 \\ = > { ({x}^{2} - x + 1)}^{2}[{ ({x}^{2} - x + 1)}^{2} - 6 {x}^{2} \times 1 + 5 {x}^{2} ]= 0 \\ = > { ({x}^{2} - x + 1)}^{2}( {x}^{4} + {x}^{2} - 1 - 2 {x}^{3} - 2x + {x}^{2} - {x}^{2} ) = 0 \\ = > { ({x}^{2} - x + 1)}^{2} ( {x}^{4} + {x}^{2} - 1 - 2 {x}^{3} - 2x )= 0 \\ = > { ({x}^{2} - x + 1)}^{2} ( {x}^{4} - 2 {x}^{3} + {x}^{2} - 2x - 1) = 0 \\ = > { ({x}^{2} - x + 1)}^{2} = 0 \\ = > {x}^{2} - x + 1 = \sqrt{0} \\ = > {x}^{2} - x + 1 = 0 \\ = > {x}^{2} - x - x + 1 = 0 \\ = > x(x - 1) - 1(x - 1) = 0 \\ = > (x - 1)(x - 1) = 0 \\ = > (x - 1) = 0 \\ = > x = 1$
