expand x\Rightarrow-2(-x^2+5x-4)

expand

x \Rightarrow - 2 (- x^{2} + 5 x - 4)

x \Rightarrow + 2 x^{2} - 10 x + 8

Solution steps

x \Rightarrow - 2 (- x^{2} + 5 x - 4)

=\Rightarrow x - 2 (- x^{2} + 5 x - 4)

Expand

- 2 (- x^{2} + 5 x - 4) : 2 x^{2} - 10 x + 8

= x \Rightarrow + 2 x^{2} - 10 x + 8

\frac{5 ^{22}}{5 ^{22}}

e^{- k} (1 - a) - e^{- 2 k} (1 - a)

\frac{1}{( x + 2 ) ^{2} ( 3 x + 6 )}

- \frac{3 y ^{2} ( - 3 y + 3 ) ^{2}}{2}

P^{1} (2, - 5)
