If a(x) = 2x - 4 and b(x) = x + 2, which of the following expressions produces a quadratic function?

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 *_*

Ithink it’s a as the answer.

8,400-6,400=xx/6,400anyways the percent increase is 31.25% or 0.3125 you can round if you can
