Question

x³-23x²+142x-120 in maths please send answer​

Answer 1

I think, your question is about factorising the polynomial. Follow these,

$\sf {x}^{3} - 23 {x}^{2} + 142x - 120$

$\sf = {x}^{3} - {x}^{2} - 22 {x}^{2} + 22x + 120x - 120$

$\sf = {x}^{2} (x - 1) - 22(x - 1) + 120(x - 1)$

$\sf = (x - 1)( {x}^{2} - 22x + 120)$

$\sf = (x - 1)( {x}^{2} - 10x - 12x + 120)$

$\sf = (x - 1)(x(x - 10) - 12(x - 10))$

$\sf = (x - 1)(x - 10)(x - 12)$

Hence, the factorised form is (x-1)(x-10)(x-12).
