Which of the choices shown are the lengths of the sides of a right triangle a) 1, 1, 2 b) 5, 6, 12 c) 3, 5, 8 d) 10, 24, 26

Option D because according to puthogrean theorem adding the two shortest sides squared should give you the longest side(hypotenuse) squared.So 10^2 plus 24^2 is 676 which is 26^2

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 *_*
