Question

y^2-xy(1-x)-x3(factorisation)
​

Answer 1

Answer:

(−x+y)(x^2+y)

Step-by-step explanation:

$= > {y}^{2} - xy(1 - x) - {x}^{3} \\ \\ by \: opening \: brakets \\ we \: have \\ \\ = > {y}^{2} -xy + {x}^{2} y - {x}^{3} \\ by \: re - arranging \\ \\ = > - {x}^{3} + {x}^{2} y - xy + {y}^{2} \\ \\ = > {x}^{2} ( - x + y) + y( - x + y) \\ \\ = > ( - x + y)( {x}^{2} + y)$
