expand sqrt(2(x^2-2x)+3)-3

expand

2 (x^{2} - 2 x) + 3 - 3

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

Solution steps

2 (x^{2} - 2 x) + 3 - 3

Expand

2 (x^{2} - 2 x) + 3 : 2 x^{2} - 4 x + 3

= 2 x^{2} - 4 x + 3 - 3

45 + 4 x^{a + 2} - x^{2 (a + 2)}

(e^{- 6 t} + 4)^{2}

(3 x = 7,) (2 x = y - 2)

A (- 10, 21) B (8, - 6)

\frac{( x - 2 y ) d x + ( 2 x + y ) d y}{x}
