4y+x+9 well its making me wrote 20 charcters s

               4y + x + 9

can't be simplified, factored, expanded, graphed, solved, or evaluated.
So what is your question ?

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 *_*
