Answer:
2.
Step-by-step explanation:
In this case, a is 2, b is 10, and c is -6.
-10 plus or minus the square root of 100 minus 4 * -12 divided by 4 = -10 plus or minus the square root of 100 - -84 / 4 = -10 plus or minus the square root of 148 / 4 = -10 plus or minus 2 and the square root of 37 / 4 = -5 plus or minus the square root of 37 / 2.
Hope this helps!
