simplify-x(x-2)+2(x-1)

simplify

- x (x - 2) + 2 (x - 1)

- x^{2} + 4 x - 2

Solution steps

- x (x - 2) + 2 (x - 1)

Expand

- x (x - 2) : - x^{2} + 2 x

= - x^{2} + 2 x + 2 (x - 1)

Expand

2 (x - 1) : 2 x - 2

= - x^{2} + 2 x + 2 x - 2

Add similar elements:

2 x + 2 x = 4 x

= - x^{2} + 4 x - 2

(- 6 - 4 i) + (1 + 4 i)

5 x^{2} - x [5 x - 3 x (x - 8) - 11] + 3

(6 - 4 i) + (5 + 3 i)

(3 b + 5 d)^{2}

- 863 + 112
