Answer:
a=√−c4−b2+2020 or a=−√−c4−b2+2020
b=√−c4−a2+2020 or b=−√−c4−a2+2020
c=cant find it
Step-by-step explanation:
Step 1 for a: Add -c^4 to both sides.
c4+a2+b2+−c4=2020+−c4
a2+b2=−c4+2020
Step 2: Add -b^2 to both sides.
a2+b2+−b2=−c4+2020+−b2
a2=−c4−b2+2020
Step 3: Take square root.
a=√−c4−b2+2020 or a=−√−c4−b2+2020
Step 1 for b: Add -c^4 to both sides.
c4+a2+b2+−c4=2020+−c4
a2+b2=−c4+2020
Step 2: Add -a^2 to both sides.
a2+b2+−a2=−c4+2020+−a2
b2=−c4−a2+2020
Step 3: Take square root.
b=√−c4−a2+2020 or b=−√−c4−a2+2020
