The legth of a room is 2m more than the width , and the area of the floor is 63 m2.find the legth and the width of the room

(2+x)*x = 63

x = 7

Therefore the length is 9 and the width is 7.

That they are numbers and related to each other.

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 *_*
