Please help!!
yarga [219]

Because this is a fourth degree that will be tricky to factor as it is, we will do a u substitution. Let x^2=u. We can now rewrite that polynomial in terms of u: u^2-7u-8=0. Filling into the quadratic formula we have u=\frac{7+/-\sqrt{49-4(1)(-8)}}{2}. Simplifying down u=\frac{7+/-\sqrt{81}}{2} and u=\frac{7+9}{2} or u=\frac{7-9}{2}. That means that u = 8 or u = -1. But don't forget that we let u=x^2, so we have to put x-squared back in for u. That gives us x^2=8 which simplifies down to +/-2\sqrt{2}. That also gives us x^2=-1. When we take the square root of -1, we have to use the fact that -1 = i^2, so we sub that in to get x=+/-i. All in all, your solutions are as follows: 2\sqrt{2},-2\sqrt{2},i,-i which is choice b.
