1. We can move 64 to the other side to get 10,000x2=64. We then divide both sides by 10,000 to get 64/10000=x2
we can then square root both sides to get 8/100=2/25.
2. We move 34x to the right side to get 9x^2+34x-8=0 you can then use the quadratic formula(or factor, I was just too lazy) to get x=-4, 2/9
3. You can also use the quadratic formula to get imaginary solutions. There are no real solutions to this one.
4. You can also use the quadratic formula to get -3.2 plus minus √14.24 all over 4.
