Question

Помогите пожалуйста!!!!!!!!!!!!!!!!!!!!!!!!!!!!!При яких значеннях х значення виразу (2х-3)(х+1) на 3 більше за значення виразу х(х-2)?​

Answer 1

Відповідь:

(2x-3)(x+1)=x(x-2)+3

2x²+2x-3x-3=x²-2x+3

x²+x-6=0

D= 1+24=25

x1= (-1+5)/2= 2

x2= (-1-5)/2= -3

Answer 2

Understanding the Expression

The given expression is (2x-3)(x+1), and we want to find the values of x for which this expression is 3 greater than the expression x(x-2).

Calculating the Expressions

To solve this, we can first calculate the values of the two expressions and then find the values of x for which the first expression is 3 greater than the second expression.

The first expression is (2x-3)(x+1), and the second expression is x(x-2).

Finding the Values of x

To find the values of x for which the first expression is 3 greater than the second expression, we can set up the equation: (2x-3)(x+1) = x(x
