x^3+24x^2+44x=0

Solution

To solve the equation x3+24x2+44x=0x^3 + 24x^2 + 44x = 0, let's start by factoring the expression.

Given:

x3+24x2+44x=0x^3 + 24x^2 + 44x = 0

Step 1: Factor out the common term xx.

x(x2+24x+44)=0x(x^2 + 24x + 44) = 0

Now, we have two factors:

  1. x=0x = 0
  2. x2+24x+44=0x^2 + 24x + 44 = 0

Step 2: Solve the quadratic equation x2+24x+44=0x^2 + 24x + 44 = 0.

We can solve this quadratic equation using the quadratic formula:

x=b±b24ac2ax = \frac{-b \pm \sqrt{b^2 - 4ac}}{2a}

For ax2+bx+c=0ax^2 + bx + c = 0, the coefficients are:

  • a=1a = 1
  • b=24b = 24
  • c=44c = 44

Substituting these into the formula:

x=24±2424(1)(44)2(1)x = \frac{-24 \pm \sqrt{24^2 - 4(1)(44)}}{2(1)}

x=24±5761762x = \frac{-24 \pm \sqrt{576 - 176}}{2}

x=24±4002x = \frac{-24 \pm \sqrt{400}}{2}

x=24±202x = \frac{-24 \pm 20}{2}

Step 3: Find the roots.

  1. x=24+202=42=2x = \frac{-24 + 20}{2} = \frac{-4}{2} = -2
  2. x=24202=442=22x = \frac{-24 - 20}{2} = \frac{-44}{2} = -22

Final Solutions:

The roots of the equation are:

x=0,x=2,andx=22x = 0, \, x = -2, \, \text{and} \, x = -22

Summary:

The solutions to the equation x3+24x2+44x=0x^3 + 24x^2 + 44x = 0 are x=0x = 0, x=2x = -2, and x=22x = -22.
