Question

3х3+2х2-5х+8х-3х3-х2-х2=36

Answer 1

Ответ:

3х3+2х2-5х+8х-3х3-х2-х2=36

4х-5х+8х-2х-2х=36

3х=36

х=12

Answer 2

Let's simplify and solve the given equation step by step:

3х3 - 3х3 + 2х2 - х2 + 8х - 5х - х2 = 36 (group like terms)

2х2 + 6х - 5х2 = 36 + х2 (combine like terms and simplify)

-5х2 - х2 - 6х = -36 (move all terms to one side)

-6х2 - 6х + 36 = 0 (divide both sides by -1 to make the leading coefficient positive)

х2 + х - 6 = 0 (factor the quadratic expression)

(х + 3)(х - 2) = 0 (apply the zero product property)

Thus, the solutions of the given equation are х = -3 and х = 2.
