I had to solve 2x^2x1 using the quad. formula. I got it down to (1 +/ the square root of neg. 8) divided by four. I broke the sq. of neg. 8 into the sq. root of 4 and the sq. root of 2. But my question is could it also be the sq. root of 4 and the sq. root of two? Is one way right or wrong? And when I go from there, I reduced this to 1+/2 times the sq. root of 2i/4. I further reduced it to 1/4 +/ 1/2 the sq. root of i/2. But I'm not sure if I reduced it properly. Could you show me? Thank you!

69: 16x^2+8x3. I inserted this into the quadratic formula and got 8+/ the square root of (8^24(16)(3)/(2 times 16). This reduced to 8+/ the square root of (64+120)/32, which further reduced to 8+/the square root of 184/32. …
