a polynomial function h(x) with integer coefficients has a leading coefficient of -2 and a constant term of -1. according to the rational root theorem, which of the following are possible roots of h(x)? 1, -1, -1/2, 1/2

step-by-step explanation:

assume that you have 3 different side lengths.   apply the pythagorean theorem here:   square each of the two shortest sides; call them a and b, so that their squares are a² and b².   also square the longest side, calling the result c².

now, if a² + b² = c² is true, the triangle is a right triangle; otherwise it is not a right triangle.
