$x^{4} -32 x^{2} -144$ will factor into the following
$( x^{2} +4)( x^{2} -36)$
Set each factor equal to 0:
$x^{2} +4=0$ or $x^{2} -36=0$
$x^{2} =-4$ $x^{2} =36$
x = +/- 2i x = +/- 6

Answer: 2i, 6, -6

(Sorry if I get something wrong, it’s straining my eyes to see what letter) 1. A 2. U 3. S 4. J 5. I 6. M 7. H 8. B 9. Y 10. L

To find where a coordinate is on a graph you need to start with the first number (x) (let’s say the coordinate is (2, -3), so 2) and find where it is ( you always find where the first number is on the x-axis and the second number on the y, remember that by x, y and x comes first.) Then, you need to find the second number (-3) then you need to find where they meet. So 2, -3 is on the letter I.

To find what coordinates a point that’s already been plotted is to see, for example, L, the two numbers that meet where L is are -4, -3, remember whatever was on the x axis comes first, -3, -4 is not the same.

Hopefully this makes sense, I don’t normally answer stuff.
