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

6 x^{2} - x

Solution steps

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

Apply rule:

(a) = a

(2 x^{2}) = 2 x^{2}

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

Apply the distributive law:

- (- a + b) = a - b

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

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

Add similar elements:

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

= 6 x^{2} - x

\frac{10}{64}

2 (6 x + 4) + 7 x

(4 - 3 m) 8

2 (2 + 1)^{2}
