Can you solve Xpower3+ 28x14x=028x-14x=0

Answer: Real solution: x=0x = 0 (or complex solutions: x=0,±i14x = 0, \pm i\sqrt{14})

Step-by-step solution

Step 1: Combine like terms

We combine the linear terms 28x28x and 14x-14x by performing 2814=1428 - 14 = 14. This simplifies the equation to x3+14x=0x^3 + 14x = 0.

Step 2: Factor out the common term

Both terms share a common factor of xx. We factor xx out of the expression, resulting in x(x2+14)=0x(x^2 + 14) = 0.

Step 3: Solve for x

Using the zero-product property, either x=0x = 0 or x2+14=0x^2 + 14 = 0. Solving x2+14=0x^2 + 14 = 0 gives x2=14x^2 = -14, which yields imaginary roots x=±i14x = \pm i\sqrt{14}. Over the real numbers, the only solution is x=0x = 0.
