Question 858736: Match each quadratic equation with the best way to solve it.
1. 5x^2 + 12x - 3 = 0 - solve by quadratic formula
2. x^2 - 4x = 8 - solve by factoring
3. 4x^2 - 25 = 0 - solve by square root method
4. x^2 - 5x + 6 = 0 - solve by completing the square

"Best way to solve", can sometimes vary, depending on what you can recognize.

Number 2:
x%5E2-4x-8=0----- TRY factoring and see what happens. Not really factorable.

Number 4:
Completing the square, too much trouble.
2%2A%28-3%29=%28-2%29%2A3=-6;
%28-2%29%28-3%29=6.
%28-2%29%2B%28-3%29=-5.
Factoring should be easiest.
