Let's solve your equation step-by-step.

9a2−310−a2=1

−10a4−3a2+9010a2=1

Step 1: Multiply both sides by 10a^2.

−10a4−3a2+90=10a2

−10a4−3a2+90−10a2=10a2−10a2(Subtract 10a^2 from both sides)

−10a4−13a2+90=0

(Use quartic formula)

a=−1.555509,1.555509

Check answers. (Plug them in to make sure they work.)

a=1.555509(Works in original equation)

a=−1.555509(Works in original equation)

Answer:

a=1.555509 or a=−1.555509
