4(2-х^2)-3х(Х+3)=8+9х-7х^2. Решите уравнение. 31 балл

Answer 1

8-4x²-3x²-9x=8+9x-7x²
8-7x²-9x=8+9x-7x²
8-7x²-9x-9x-8+7x²=0
-18x=0
18x=0
x=0

Answer 2

I can help you with solving equations. Here is the detailed solution for your equation:

4(2-x^2)-3x(x+3)=8+9x-7x^2

Expand the brackets:

8-4x^2-3x^2-9x=8+9x-7x^2

Simplify by collecting like terms:

-7x^2-9x+8=-7x^2+9x-8

Add 7x^2-9x+8 to both sides:

0=0

This means that the equation is true for any value of x. The solution is x ∈ R, where R is the set of all real numbers.Ответь+подробно.+4(2-х^2)-3х(Х+3)=8+9х-7х^2.+Решите+уравнение.+31+балл
