expand (x^2+4x-2)-(-x^2-2x=4)

expand

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

2 x^{2} + 6 x - 2 = 4

Solution steps

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

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

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

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

Expand

(x^{2} + 4 x - 2) + x^{2} + 2 x : 2 x^{2} + 6 x - 2

2 x^{2} + 6 x - 2 = 4
