Question

can anyone do B part of this question.........................if anyone give right answer i will mark him brainlist answer​

Answer 1

a.

$= 6 {x}^{3} + 4 {x}^{2} - 2x \\ = 6 {x}^{3} + 6 {x}^{2} - 2{x}^{2} - 2x \\ = 6 {x}^{2} (x + 1) - 2x(x + 1) \\ = (x + 1)(6 {x}^{2} - 2x) \\ = 2x(3x - 1)(x + 1)$

b.

${x}^{7} + {x}^{6} + {x}^{5} + {x}^{4} \\ {x}^{6} (x + 1) + {x}^{4} ( {x}^{} + 1) \\ (x + 1)( {x}^{6} + {x}^{4}) \\ {x}^{4} ( {x}^{2} + 1)(x + 1)$
