Question

$( - 3 {x}^{2} - 1 \times ( - x + 9)$
​

Answer 1

$\color{hotpink} \huge \boxed{ - {3x}^{2} - 1 \times ( - x + 9)}$

$\color{hotpink} \huge \boxed{ - {3x}^{2} + x - 9}$

Now factorise these by completing square method ...

$a = > - 3 \\ b = > + 1 \\ c = > - 9$

$\color{red} \huge \boxed{d = {b}^{2} - 4ac}$

$d = > ( {1)}^{2} - 4 \times - 3 \times - 9 \\ \\ d = > 1 - 108 \\ \\ d = > - 107$

D<0
