Question

(3x^2-x+5)(x^2-x-1)​

Answer 1

$\huge \tt{\underline{ \underline{Answer :}}}$

$(3x^2-x+5)(x^2-x-1)$

$3 {x}^{2} (x^2-x-1) - x(x^2-x-1) + 5(x^2-x-1)$

$3 {x}^{4} - 3 {x}^{3} - 3 {x}^{2} - {x}^{3} + {x}^{2} + x + 5 {x}^{2} - 5x - 5$

$3 {x}^{4} \underline{ - 3 {x}^{3} - {x}^{3} } - \underline{3 {x}^{2} + {x}^{2} + 5 {x}^{2}} + \underline{ x - 5x }- 5$

$\large \boxed{{{3 {x}^{4} - 4 {x}^{3} + 3 {x}^{2} - 4x - 5}}}$
