12x=x^2-64
you have to do quadratic formula

Example: 3/4 divided by 6/8
Step 1: keep 3/4
Step two: change the division sign to a multiplication sign
Step 3: flip 6/8 and make it 8/6
Step 4: multiply it, then that’s your answer to the division problem
<span> Just plug in the value of b=3 in 4b^4, then you solve it, and your answer is 324</span>
