Which step can you use to solve the equation m+9=−2?

First, let us define electronegativity. electronegativity is "the ability of an atom to attract electrons." in addition, electronegativity increases in elements from left to right, while on the other hand, electronegativity decreases from top to bottom in an element group. it decreases because the atomic radius increases as we go downward an element in the group.

Ithink it would be -7

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 *_*
