Answer» let alpha= p , bita = qax^2+bx+Cp+q= -b/apq= c/a1/p^2+1/q^2=p^2×q^2/p^2q^2= (p+q)^2-2pq÷(pq)^2=(-b/a)^2-2(C/a)÷ c^2/a^2=b^2/a^2-2c/a×a^2/c^2= b^2 let p= alpha q= bitaax^2+bx+Csum of zeros p+q= -b/aproduct of zeros= C/a1/p^2+1/q^2=p^2+q^2/p^2q^2= (p+q)^2-2pq/p^2q^2= b^2/a^2-2c/a÷c^2/a^2= b^2-2ac/a^2×a^2/c^2=b^2-2ac/c^2 |
