Question

(2x^3+x-5)+(x^3-3x) сложите многочлены

Answer 1

(2x³ + x - 5) + (x³ - 3x) = 2x³ + x - 5 + x ³ - 3x = 3x ³ - 2x - 5

Answer 2

(2x³+x-5)+(x³-3x)=2x³+x-5+x³-3x=3x³-2x-5

Answer 3

To add the polynomials, simply combine like terms:

(2x^3 + x - 5) + (x^3 - 3x)

First, group the terms with the same power of x:

(2x^3 + x^3) + (x - 3x) - 5

Now, combine the like terms:

3x^3 - 2x - 5

So, the sum of the two polynomials is 3x^3 - 2x - 5.
