Question

45+32x+5x² = 3x - 15+10x.​

Answer 1

Ответ:

нет корней

Объяснение:

45+32x+5x² = 3x-15+10x

45+32x+5x²-3x+15-10x = 0

5x²+19x+60 = 0

D = 361-1200 = -839

D < 0, уравнение не имеет корней

Answer 2

It seems like you have a quadratic equation there. To solve for the value(s) of 'x', we need to rearrange the equation into the standard quadratic form, which is ax² + bx + c = 0. In your case, the equation is:

5x² + (32x - 3x) + (-15 + 10x + 15) = 0

Now simplify the equation:

5x² + 29x + 0 = 0

Since the coefficient of the squared term is not zero, we can solve this quadratic equation using the quadratic formula:

x = (-b ± √(b² - 4ac)) / 2a

In this equation, a = 5, b = 29, and c = 0. Plug these values into the formula:

x = (-29 ± √(29² - 4 * 5 * 0)) / (2 * 5) x = (-29 ± √(841)) / 10 x = (-29 ± 29) / 10

This gives us two possible solutions for 'x':

1. x = (-29 + 29) / 10 = 0 / 10 = 0
2. x = (-29 - 29) / 10 = -58 / 10 = -5.8

So, the solutions for the equation 5x² + 29x = 0 are x = 0 and x = -5.8.
