simplify (-6x-2x^3-10x^{211})-(7x^3+2x^2+3x-12)

simplify

(- 6 x - 2 x^{3} - 10 x^{211}) - (7 x^{3} + 2 x^{2} + 3 x - 12)

- 10 x^{211} - 9 x^{3} - 2 x^{2} - 9 x + 12

Solution steps

(- 6 x - 2 x^{3} - 10 x^{211}) - (7 x^{3} + 2 x^{2} + 3 x - 12)

Apply rule:

(a) = a

(- 6 x - 2 x^{3} - 10 x^{211}) = - 6 x - 2 x^{3} - 10 x^{211}

= - 6 x - 2 x^{3} - 10 x^{211} - (7 x^{3} + 2 x^{2} + 3 x - 12)

Apply the distributive law:

- (a + b) = - a - b

- (7 x^{3} + 2 x^{2} + 3 x - 12) = - 7 x^{3} - 2 x^{2} - 3 x + 12

= - 6 x - 2 x^{3} - 10 x^{211} - 7 x^{3} - 2 x^{2} - 3 x + 12
