Answer 1

Ответ:

( 25х - 20x + 4 ) ( x - x ) > 0

( 25х - 20x + 4 ) · 0 > 0

0 > 0. это неверно. неравенство не имеет решений. ∅

Answer 2

To solve the inequality (25x - 20x + 4)(x - x) > 0, let's simplify the expression first.

The expression (x - x) is equal to 0 since any number subtracted by itself results in zero.

So, we are left with (25x - 20x + 4) * 0 > 0.

Since any number multiplied by zero is zero, the left-hand side of the inequality is always zero, which means it can never be greater than zero.

Therefore, there is no solution to the inequality (25x - 20x + 4)(x - x) > 0.
