3x^2 +5x - 3 - 3x^2 - 3x  -12 = 0          <- 3x^2 -- 3x^2 сокращается

 

 

2x - 15 = 0

 

2x = 15

 

x = 15:2

 

x = 15/2 = 7,5

 

 

 

Answer 2

To solve the given equation:

(3X^2 + 5X - 3) - 3(X^2 + X + 4) = 0

First, we need to simplify the left-hand side of the equation by multiplying out the brackets:

3X^2 + 5X - 3 - 3X^2 - 3X - 12 = 0

Simplifying further, we can combine like terms:

0X^2 + 2X - 15 = 0

Now we can solve for X by using the quadratic formula:

X = (-b ± sqrt(b^2 - 4ac)) / 2a

where a = 0, b = 2, and c = -15.

Plugging in these values, we get:

X = (-2 ± sqrt(2^2 - 4(0)(-15))) / 2(0)

X = (-2 ± sqrt(124)) / 0

Since dividing by zero is undefined, we can conclude that there is no solution to this equation.
