Question

Х-2.3/(1.9-х) (х-1.3)

Answer 1

Ответ:

$\frac{100x-230}{-100x^2+320x-247}$

Answer 2

To simplify the expression, let's perform the algebraic manipulation step by step:

1. Distribute the factor (x - 1.3) across the expression (x - 2.3) / (1.9 - x):

(x - 2.3) / (1.9 - x) * (x - 1.3)

2. Expand the expression by multiplying the numerators and denominators:

(x * (x - 1.3) - 2.3 * (x - 1.3)) / (1.9 - x)

3. Simplify the terms in the numerator:

(x^2 - 1.3x - 2.3x + 2.99) / (1.9 - x)

4. Combine like terms in the numerator:

(x^2 - 3.6x + 2.99) / (1.9 - x)

Now the expression is in its simplified form: (x^2 - 3.6x + 2.99) / (1.9 - x)
