Question

Can someone solve it step by step for me please?

Answer 1

Okay, this is a simplified version of how to solve this complicated equation.

First add like terms but in this equation is not very efficient when solving.

So subtract the -2x squared from both sides and the equation should like mine

x⁴ + 4x³ + 12x + 45 = x ² -2x ² + 6x + 9

So keep the left side of the equation the same, but change the right like this because your adding the x squared.

-x² + 6x + 9

Now go back to the whole equation

x⁴ + 4x³ + 12x + 45 = -x² + 6x + 9

You can’t do anything on the left side of the equation do the same process with the other numbers like this:

x⁴ + 4x³ + 12x = -x² + 6x + 9 -45

You subtract the 45 from each side and it’s negative on the other side because you subtracted it.

Now add the 9 and -45 = -36

Now the equation should look like this:

x⁴ + 4x³ + 12x = -x² + 6x -36

Subtract -12x from each side and the 12x on the left side of the equation is canceled out and is gone

The equation should look like this:

x⁴ + 4x³ + = -x² + 6x -36 -12x

Then add the 6x and -12x because they are like terms

So this is the final simplified version of the complex problem

x⁴ + 4x³ + = -x² + -36 -6x

You can’t add any other like terms to find the value of x because x and x² can’t be added together
