simplify (4n-3n^3)-(3n^3+4n)

simplify

(4 n - 3 n^{3}) - (3 n^{3} + 4 n)

- 6 n^{3}

Solution steps

(4 n - 3 n^{3}) - (3 n^{3} + 4 n)

Apply rule:

(a) = a

(4 n - 3 n^{3}) = 4 n - 3 n^{3}

= 4 n - 3 n^{3} - (3 n^{3} + 4 n)

Apply the distributive law:

- (a + b) = - a - b

- (3 n^{3} + 4 n) = - 3 n^{3} - 4 n

= 4 n - 3 n^{3} - 3 n^{3} - 4 n

Add similar elements:

- 3 n^{3} - 3 n^{3} = - 6 n^{3}

= 4 n - 6 n^{3} - 4 n

Group like terms

= - 6 n^{3} + 4 n - 4 n

Add similar elements:

4 n - 4 n = 0

= - 6 n^{3}
