Free Online Square Root calculator - Find square roots of any number step-by-step
The square root calculator finds the square root of the given radical expression. If a given number is a perfect square, you will get a final answer in exact form. If a given number is not a perfect square, you will get a final answer in exact form and decimal form.
So, x=2 is the root of the equation. Now we have to divide polynomial by x-ROOT. In this case we divide 2x 3 -x 2 -3x+6 by x-2. Now we use 2x 2 -3 to find remaining roots. To solve cubic equations, we usually use the factoring method. Example 05: Solve equation 2x 3 -4x 2 -3x+6=0.
