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

Multiply everything inside the bracket by negative 1

$(- 1) \times (+ x^{2}) = - x^{2}$ $(-1)xx(+x^2)=color(red)(-x^2)$

$(- 1) \times (- 2 x) = + 2 x$ $(-1)xx(-2x)=color(red)(+2x)$

$(- 1) \times (+ 5) = - 5$ $(-1)xx(+5) =color(red)( -5)$

Putting it all together we have:

$- x^{2} + 2 x - 5$ $color(red)(-x^2+2x-5)$

How do you simplify −1(x2−2x+5)-1(x^2-2x+5)?
