The lcm of two numbers is the product of the two numbers. always, sometimes or never true give two reasoning

Sometimes.sometimes it is true, for example, the lcm of 2 and 3 is 6=2×3.sometimes it is false, for example, the lcm of 2 and 4 is 4, which is not equal to 2×4

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 *_*
