Question

2x^2-5x+a-2=0 .найти a

Answer 1

2x²-5x+a-2=0

D=5²-4·2·(a-2)=25-8a+16=41-8a

при D (дискриминант) больше или равно нулю уравнения имеет решение

D=41-8a≥0

41-8a≥0

41≥8a

8a≤41

a≤$\frac{41}{8}$

a≤5.125

a∈(-∞;5.125)

Ответ: при значениях a≤5.125 уравнение имеет решение

Answer 2

To find the value of 'a' in the equation 2x^2 - 5x + a - 2 = 0, we need additional information or context. The equation has only one variable 'x', and without any other constraints or conditions, there are infinitely many values of 'a' that could satisfy the equation.

If you have more details about the equation or any conditions related to 'x' or 'a,' please provide them, and I'll be happy to help you find the value of 'a.'
