First this quartic function can be factored just like a quadratic equation. Now because neither factor can be factored further and there is no term we can set each equal to zero and solve. Feb 22 2018.

First put into descending powers. Now factor out 3x leaving. 3x x2x-9 0.

So clearly x0 is one solution. Use the quadratic formula to find the others. You know they are real since the discriminant is positive.

Sometimes it is easier to find solutions or roots of a quadratic equation by factoring. Indeed the basic principle to be used is. If a and b are real or complex numbers such that ab0 then a0 or b0.

Solve the equation Solution. Factoring yields the equation. Hence we have which yield.

Using this property we can see how to divide two complex numbers. Lets look at the example. The magic trick is to multiply numerator and denominator by the complex conjugate companion of the denominator in our example we multiply by 1i.

Since 1i1-i2 and 23i1i-15i we get. And we are done. Correct answer to the question Find the real or imaginary solutions by factoring.
