Solve each given equation and show your work. tell whether it has one solution, an infinite number of solutions, or no solutions, and identify each equation as an identity, a contradiction, or neither.
6x+3x-6=10x-x-6
25-5x=12-3x+13+8x
4x+8=x+5+7x-4

I think this is the answer to your question .
1. one solution
2. no solution
3.one solution

Answer to your question: a. the fundamental theorem of algebra tells you that the equation will have two complex roots since the degree of the polynomial is 2. the roots are ​ x=1±i7√2 .number of roots=degree of polynomialhere, degree of polynomial is 2 so number of roots will be 2.hope it *_*
