Answer 2

Ответ:

(х-5)(х+6)>(х+10)(х-9)=х2+6х-5х-30>х2-9х+10х-90=х2+х-х2-х>-90+30=0>-60

Answer 3

To solve the inequality (x - 5)(x + 6) > (x + 10)(x - 9), we can simplify the expression and then solve for the values of x that satisfy the inequality.

Expanding the expressions on both sides:

(x - 5)(x + 6) > (x + 10)(x - 9) x^2 + 6x - 5x - 30 > x^2 - 9x + 10x - 90 x^2 + x - 30 > x^2 + x - 90

Now, subtracting x^2 and x from both sides:

-30 > -90

Since -30 is not greater than -90, the inequality -30 > -90 is false. Therefore, the inequality (x - 5)(x + 6) > (x + 10)(x - 9) is false for all values of x.
