Question

( x-3) • (x+3)=x•(x-2) помогите плиз​

Answer 1

Ответ:

4,5

Пошаговое объяснение:

(x-3)(x+3)=x(x-2)

${x}^{2} - 9 = {x}^{2} - 2x$

${x}^{2} - {x}^{2} + 2x = 9$

$2x = 9$

$x = \frac{9}{2}$

$x = 4 \frac{1}{2} = 4.5$

Answer 2

I can help you with your math problem. To solve it, you need to expand the brackets and simplify the expression. Here are the steps:

$$ (x-3)(x+3) = x(x-2) $$

$$ x^2 - 9 = x^2 - 2x $$

$$ -9 = -2x $$

$$ x = \frac{9}{2} $$

The solution is $x = \frac{9}{2}$. I hope this helps.Ответь+подробно.++(+x-3)+•+(x+3)=x•(x-2)+помогите+плиз​+
