Active 1 year, 4 months ago. Square root of -1 is also not a real number, and therefore it is referred to as an imaginary number. Let S Be The Sum Of The Two Numbers. In order to determine the positive number of real zeroes, we must count the number of sign changes in the coefficients of the terms of the polynomial after substituting for The number of real zeroes can then be any positive difference of that number and a positive multiple of two. If a, b, c are positive real numbers such that a + b + c = p, then 1/a+1/b+1/c is greater than asked Dec 1, 2020 in Linear Equations by Harithik ( 21.6k points) linear inequalities The reason that we have two square roots is exemplified above. I tried A(A>0) but it returns positive number but also complex numbers whose real part is positive… (The same thing goes for other subalgebras ? If p p is a complex number , then we may use the usual quasiorder and partial order on the complex plane , or equivalently require first that p p is real and then use the definitions for a real number.
