Answer 2

I can help you solve this equation. First, let's expand the brackets and simplify the terms:

$$(5-x)^2 - (3x-2)(2x+1) = x(2-5x)$$ $$25 - 10x + x^2 - 6x^2 - 5x + 2 = 2x - 5x^2$$ $$-4x^2 - 13x + 27 = 0$$

Next, let's use the quadratic formula to find the values of $x$ that satisfy the equation:

$$x = \frac{-b \pm \sqrt{b^2 - 4ac}}{2a}$$ $$x = \frac{13 \pm \sqrt{13^2 - 4(-4)(27)}}{2(-4)}$$ $$x = \frac{13 \pm \sqrt{529}}{-8}$$ $$x = \frac{13 \pm 23}{-8}$$

Therefore, the solutions are:

$$x_1 = \frac{13 + 23}{-8} = -4.5$$ $$x_2 = \frac{13 - 23}{-8} = 1.25$$

I hope this helps you understand how to solve the equation. If you have any other questions, feel free to ask me.Ответь+подробно.+Решите+уравнение++(+5+-+х)^2+-+(3х+-+2+)+*+(+2х+++1)+=+х+*+(+2+--5х)
