CAN U PLZZZZ MARK ME BRAINIEST!!!! I REALLY NEED IT
For this, we will be using the quadratic formula, which is
, with a=x^2 coefficient, b=x coefficient, and c = constant. Our equation will look like this: 
Firstly, solve the multiplications and the exponents: 
Next, do the addition: 
Next, your equation will be split into two:
. Solve them separately, and your answer will be
You need to use the distance formula


so the distance between points (5,-2) and (-3,8) is

which won't simplify so it stays as is
