Question

16³+8x²+x=0 умоляю помогите​

Answer 1

Ответ:

16x³+8x²+x=0

x(16x²+8x+1)=0

x(4x+1)²=0

x=0

4x+1=0

x=-1/4

Answer 2

To solve the equation 16³ + 8x² + x = 0, we need to find the values of x that satisfy the equation. Let's break down the steps to solve this equation:

Step 1: Simplify the equation

First, let's simplify the equation by combining like terms. The equation becomes:

4096 + 8x² + x = 0

Step 2: Rearrange the equation

Next, let's rearrange the equation so that it is in standard quadratic form, which is ax² + bx + c = 0. The equation becomes:

8x² + x + 4096 = 0

Step 3: Solve the quadratic equation

To solve the quadratic equation, we can use the quadratic formula:

x = (-b ± √(b² - 4ac)) / (2a)

In this case, a = 8, b = 1, and c = 4096. Substituting these values into the quadratic formula, we get:

x = (-1 ± √(1² - 4 * 8 * 4096)) / (2 * 8)

Simplifying further:

x = (-1 ± √(1 - 131072)) / 16

x = (-1 ± √(-131071)) / 16

Since the discriminant (b² - 4ac) is negative, the quadratic equation has no real solutions. Therefore, the equation 16³ + 8x² + x = 0 has no real solutions.

I hope this helps! Let me know if you have any further questions.
