WebFeb 2, 2024 · Proof. Let ABC and A B C be in different planes π and π respectively. Since BB and CC intersect in O, it follows that B, B, C and C lie in a plane . Thus BC must meet B C in a point L . By the same argument, CA meets C A in a point M and AB meets A B in a point N . These points L, M, N are in each of the planes π and π . WebThe factor theorem states that if f(x) is a polynomial of degree n greater than or equal to 1, and 'a' is any real number, then (x - a) is a factor of f(x) if f(a) = 0. Factor theorem is mainly used to factor the polynomials and to find the n roots of the polynomials. 1-to-1 Tutoring. Math Resources. Resources. futhead player search https://waneswerld.net
