What is b when 25b2 minus b4 equal 144?
b can be equal to 3 or 4: 25*3*3 - 3*3*3*3 = 225 - 81 = 144. 25*4*4 - 4*4*4*4 = 400 - 256 = 144. That is correct. I knew it was 3 and 4. But I need the method by which one can calculate the answer. Thank you. You can rearrange the terms set this up as a quadratic equation and solve for b2 Let x = b2, then 25b2 - b4 = 144 can be rewritten as -x2 + 25x -144 = 0, and a = -1, b = 25, and c = -144 Plugging into the quadratic equation, we get: x = (-25 +/- sqrt(25^2 - 4*-1*-144)) / 2*-1 x = (-25 +/- sqrt(625 - 576) ) / -2 x = (-25 +/- 7) / -2 x = -18/-2 = 9, or x = -32/-2 = 16 and since x = b2, then b = 3 or 4
