Question

(x +11) (x-2)-(x +5)(x+ 4)=2​

Answer 1

Ответ:

(×+11)(×-2)-(×+5)(×+4)=2

×^2-2×+11×-22-×^2-4×-5×-20-2=0

-44=0(не равен)

Answer 2

Let's solve the given equation step by step:

Expand the left side of the equation: (x + 11)(x - 2) - (x + 5)(x + 4) = 2

Using the distributive property, we have: (x * x + 11 * x - 2 * x - 22) - (x * x + 5 * x + 4 * x + 20) = 2

Simplifying further: (x^2 + 9x - 22) - (x^2 + 9x + 20) = 2

Remove the parentheses: x^2 + 9x - 22 - x^2 - 9x - 20 = 2

Combine like terms: -22 - 20 = 2

-42 = 2

However, we have reached a contradiction since -42 is not equal to 2. Therefore, the given equation has no solution.
