Proof:
Suppose P is different from O, then in triangles OPM and OPN, OP=OP (common side) (given) ( given) (AAS congruency theorem) Hence, PM=PN ( CPCT) If P coincides with O, then it is equidistant from AB and CD, since they intersect at O P is equidistant from AB and ..

x.(x+y) = (x + 0)(x + y) 2(a) (Refer to Axion in previous topic) = x + (0.y) Axiom 4(a) = x + (y.0) Axiom 3(b) = x + 0 (Theorem 2) = x Axiom 2..
Proof:
When p(x) is divided by x-a, R = p(a) (by remainder theorem) p(x) = (x-a).q(x)+p(a) (Dividend = Divisor x quotient + Remainder Division Algorithm) But p(a) = 0 is given. Hence p(x) = (x-a).q(x) Conversely if x-a is a factor of p(x) then p(a)=0. p(x) = (x-a).q(x) + R If (x-a) is a facto..
