Question

( х + 4 ) • ( х - 3 ) = 0 ПОМОГИТЕ ПОЖАЛУЙСТА!!!

Answer 1

Х^2 + 4x - 3x - 12 = 0
x*2 + x - 12 = 0
D = 1 - 4 *-12 = 1 + 48 = 49;   √D = 7
x1 = (-1 +7)/2 = 3
x2 = (- 1 - 7)/2 = - 4 

Answer 2

( х + 4 ) • ( х - 3 ) = 0
Произведение равно нулю, только если один из множителей равен нулю. Значит
х+4=0 или х-3=0
х=-4           х=3
Ответ:-4;3

Answer 3

Problem Statement

You have the equation x + 4 • (x - 3) = 0 and you need help solving it.

Solution

To solve the equation x + 4 • (x - 3) = 0, we can follow these steps:

1. Distribute the multiplication: x + 4x - 12 = 0

2. Combine like terms: 5x - 12 = 0

3. Add 12 to both sides of the equation: 5x = 12

4. Divide both sides of the equation by 5: x = 12/5

Therefore, the solution to the equation x + 4 • (x - 3) = 0 is x = 12/5.
