Solve (x + 4 < 9) ∩ (x - 4 > -6). {x | -2 < x < 5} {x | x < 5 or x > -2} {all real numbers}

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 *_*
