Question

if pand q are the zeroes of a quadratic polynomial ax2 +bx+c, then evaluate the following:
1) p-q
2)p÷q +q÷ p
3) 1÷ p3 +1÷ q3
4) p2 ÷q2+ q2÷p2
​

Answer 1

Answer:

Step-by-step explanation:

ax²+bx+c

P and q are zeroes

Therefore p+q=-b/a

PQ=c/a

I) p-q

(p-q)²=p²+q²+2pq

(P-q)²=[(p+q)²-2pq]+2pq. Here (a+b)²=a²+b²+2ab so a²+b²=(a+b)²-2ab

(P-q)²=(-b/a)²

P-q=√b²/a²

p-q=b/a

ii) iii) iv) homework
