Answer:a= √b2+4bx+4×2 or a=−√b2+4bx+4×2
Let’s solve for a.
4×2+4bx−(a2−b2)=0
Step 1: Add -b^2 to both sides.
−a2+b2+4bx+4×2+−b2=0+−b2
−a2+4bx+4×2=−b2
Step 2: Add -4bx to both sides.
−a2+4bx+4×2+−4bx=−b2+−4bx
−a2+4×2=−b2−4bx
Step 3: Add -4x^2 to both sides.
−a2+4×2+−4×2=−b2−4bx+−4×2
−a2=−b2−4bx−4×2
Step 4: Divide both sides by -1.
−a2
−1
=
−b2−4bx−4×2
−1
a2=b2+4bx+4×2
Step 5: Take square root.
a=√b2+4bx+4×2 or a=−√b2+4bx+4×2
