Factor both quadratic expressions. (x 4 + 5x 2 - 36)(2x 2 + 9x - 5) = 0

So focusing on x^4 + 5x^2 - 36, we will be completing the square. Firstly, what two terms have a product of -36x^4 and a sum of 5x^2? That would be 9x^2 and -4x^2. Replace 5x^2 with 9x^2 - 4x^2:

Next, factor x^4 + 9x^2 and -4x^2 - 36 separately. Make sure that they have the same quantity inside of the parentheses:

Now you can rewrite this as , however this is not completely factored. With (x^2 - 4), we are using the difference of squares, which is . Applying that here, we have . x^4 + 5x^2 - 36 is completely factored.

Next, focusing now on 2x^2 + 9x - 5, we will also be completing the square. What two terms have a product of -10x^2 and a sum of 9x? That would be 10x and -x. Replace 9x with 10x - x:

Next, factor 2x^2 + 10x and -x - 5 separately. Make sure that they have the same quantity on the inside:

Now you can rewrite the equation as . 2x^2 + 9x - 5 is completely factored.

0.84 dang lotta people are looking for this lol or if you round up its 1 but the overall answer to that is 0.84
