P Over Q Math

Now run through each one via synthetic division. If px is a polynomial with integer coefficients and if is a zero of px p 0 then p is a factor of the constant term of px and q is a factor of the leading coefficient of px.

Every rational root of p x is one of the following 4 choices.

P over q math. In algebra the rational root theorem or rational root test rational zero theorem rational zero test or pq theorem states a constraint on rational solutions of a polynomial equation with integer coefficients and. These are the only four numbers with p dividing 2 and q dividing 1. We can use the rational zeros theorem to find all the rational zeros of a polynomial.

So now we have to construct all possibilities for p p30 or p15 or p10 or p2 or p3 or p5 or p6 or p1. Im not sure if im doing any of it right but i have all but one problem solved. By the rational root theorem the only possible rational roots are of the form pq where p is one of those values listed above and same with q.

Consequently the polynomial has 2 rational roots. We can now check each one of them. The coefficient is 1 so 1 factors into 11 only which means our solution pq must have q1.

Now the constant term is 30 30235. The points p q and r are the centres of the three triangles. So now lets try to check all possible roots for 1.

It should not take long to realize what the 3 roots are there are exactly 3 roots. Solutions of the equation are also called roots or zeroes of the polynomial on. The instructions are use the p over q method and synthetic division to factor the polynomial px and then solve px0.

Three equilateral triangles abc ayx and xzb are drawn with the point x a moveable point on ab. X 1 and x 1 are the only rational zeros of the polynomial p x.
