##### how to i solve for this varible

indicated variable a2+b2=c2 that all squared

It is not clear which variable you want to solve for, so I'll do all three:

If you want to solve for a, you need to subtract b^2 from both sides:

a^2 = c^2 - b^2

And then take the square root:

a = sqrt(c^2-b^2)

--------------------------------

If you want to solve for b, you need to subtract a^2 from both sides:

b^2 = c^2 - a^2

And then take the square root:

b = sqrt(c^2 -a^2)

-------------------------------

Finally, if you want to solve for c, you need to just take the square root:

c = sqrt(a^2 + b^2)

Please let me know if you need any clarification. Always glad to help!

we were solving for (a) only, not a^2

That's the answer provided in bold:

a = sqrt(c^2-b^2)
