Question 665004: in my text book it is written that the expression is a linear polynomial with degree 1
but my doubt is that how is this possible
according to my doubt is not a linear polynomial as this expression is having a sqrt in the variable. if an expression is having sqrt then its power will be negative. according to the the definition of polynomials there shoud'nt be a negative integral exponent for variables. so is not a polynomial.if it is not a polynomial we cant call it as a linear polynomial.this is my statement
then how is that in the book(maths grade 8 oxford) it is mentioned is a linear polynomial with degree 1. pls explain me
