Question

3x³-2x+5 і 3x³-7 знайти суму многочлела

Answer 1

3x³-2x+5+3x³-7=6x³-2x-2

Answer 2

2*x^3 -5*х^2 - 3*x = 0; x*(2*x+1)*(x-3)=0; x1=0; x2=-0,5; x=3

Answer 3

To find the sum of the two polynomials, you need to add the like terms together. First, let's write down the two polynomials:

1. Polynomial 1: 3x³ - 2x + 5
2. Polynomial 2: 3x³ - 7

Now, let's combine the like terms:

(3x³ - 2x + 5) + (3x³ - 7)

To add the two polynomials, simply combine the coefficients of the like terms:

(3x³ + 3x³) + (-2x) + 5 - 7

Now, add the coefficients:

6x³ - 2x - 2

So, the sum of the two polynomials is: 6x³ - 2x - 2.
