c2eos2(15 + 3x)(35 + -1x) = 1

Multiply (15 + 3x) * (35 + -1x)
c2eos2(15(35 + -1x) + 3x * (35 + -1x)) = 1
c2eos2((35 * 15 + -1x * 15) + 3x * (35 + -1x)) = 1
c2eos2((525 + -15x) + 3x * (35 + -1x)) = 1
c2eos2(525 + -15x + (35 * 3x + -1x * 3x)) = 1
c2eos2(525 + -15x + (105x + -3x2)) = 1

Combine like terms: -15x + 105x = 90x
c2eos2(525 + 90x + -3x2) = 1
(525 * c2eos2 + 90x * c2eos2 + -3x2 * c2eos2) = 1
(525c2eos2 + 90c2eos2x + -3c2eos2x2) = 1

Solving
525c2eos2 + 90c2eos2x + -3c2eos2x2 = 1

Solving for variable 'c'.

Move all terms containing c to the left, all other terms to the right.
