Question

x cube- 4 x square - 7 x + 10 factorise​

Answer 1

Solution:

$\sf{{x}^{3} - {4x}^{2} - 7x + 10}$

$\sf{ {x}^{3} - {x}^{2} - {3x}^{2} + 3x - 10x + 10}$

$\sf{ {x}^{2} (x - 1) - 3x(x - 1) - 10(x - 1)}$

$\sf{(x - 1)( {x}^{2} - 3x - 10)}$

$\sf{(x - 1)( {x}^{2} + 2x - 5x - 10)}$

$\sf{(x - 1)[x(x + 2) - 5(x + 2)]}$

$\sf{(x - 1)(x + 2)(x - 5)}$
