Zeroes of a polynomial p(x) is real number ‘a’ for which polynomial p(x) if p(a) = 0.

E.g.: For p(x) = x-2 , p(2) = 2-2 =0. Thus 2 is zeroes for polynomial p(x)= x-2

Note: Every real number is a zero of the zero polynomial p(x)=0.

Hema Addapaka 5 years, 3 months ago

sum of angles of a quadrilateral is 360

x + x+3 + x+8 + x+9 = 360

4x +20 = 360

4x = 360-20

4x = 340

x = 340/4
