\left(2x-1\right)\times 2\left(3c-2\right)+\left(x^{2}-4\right)\times 3=\left(x-2\right)\left(2x-1\right)\left(x+2\right)
Multiply both sides of the equation by \left(x-2\right)\left(2x-1\right)\left(x+2\right), the least common multiple of x^{2}-4,2x-1.
\left(4x-2\right)\left(3c-2\right)+\left(x^{2}-4\right)\times 3=\left(x-2\right)\left(2x-1\right)\left(x+2\right)
Use the distributive property to multiply 2x-1 by 2.
12xc-8x-6c+4+\left(x^{2}-4\right)\times 3=\left(x-2\right)\left(2x-1\right)\left(x+2\right)
Use the distributive property to multiply 4x-2 by 3c-2.
12xc-8x-6c+4+3x^{2}-12=\left(x-2\right)\left(2x-1\right)\left(x+2\right)
Use the distributive property to multiply x^{2}-4 by 3.
12xc-8x-6c-8+3x^{2}=\left(x-2\right)\left(2x-1\right)\left(x+2\right)
Subtract 12 from 4 to get -8.
12xc-8x-6c-8+3x^{2}=\left(2x^{2}-5x+2\right)\left(x+2\right)
Use the distributive property to multiply x-2 by 2x-1 and combine like terms.
12xc-8x-6c-8+3x^{2}=2x^{3}-x^{2}-8x+4
Use the distributive property to multiply 2x^{2}-5x+2 by x+2 and combine like terms.
12xc-6c-8+3x^{2}=2x^{3}-x^{2}-8x+4+8x
Add 8x to both sides.
12xc-6c-8+3x^{2}=2x^{3}-x^{2}+4
Combine -8x and 8x to get 0.
12xc-6c+3x^{2}=2x^{3}-x^{2}+4+8
Add 8 to both sides.
12xc-6c+3x^{2}=2x^{3}-x^{2}+12
Add 4 and 8 to get 12.
12xc-6c=2x^{3}-x^{2}+12-3x^{2}
Subtract 3x^{2} from both sides.
12xc-6c=2x^{3}-4x^{2}+12
Combine -x^{2} and -3x^{2} to get -4x^{2}.
\left(12x-6\right)c=2x^{3}-4x^{2}+12
Combine all terms containing c.
\frac{\left(12x-6\right)c}{12x-6}=\frac{2x^{3}-4x^{2}+12}{12x-6}
Divide both sides by 12x-6.
c=\frac{2x^{3}-4x^{2}+12}{12x-6}
Dividing by 12x-6 undoes the multiplication by 12x-6.
c=\frac{x^{3}-2x^{2}+6}{3\left(2x-1\right)}
Divide 2x^{3}-4x^{2}+12 by 12x-6.
