Question

if m and n are zeroes of the polynomial 3x×x+11x-4. find the value of m/n+n/m

Answer 1

m/n+n/m = m²+n²/mn
= (m+n)²-2mn/mn
= (-b/a)²-2(c/a)÷c/a
= (-11/3)²-2(-4/3)÷-4/3
=121/9+8/3 ÷ -4/3
=121+24/9÷-4/3
=145/9÷-4/3
= -145/9×3/4
= -145×4/3
= -580/3
= -193.3333333

here is ur answer

Answer 2

Answer:

Step-by-step explanation:

m/n + n/m

m ^{2} + n^{2}/mn

(m+n)∧2 - 2mn/mn

(-11/3)∧2 - 2ˣ(-4/3)/(-4/3)

121/9 +8/3 / -4/3

145/9/-4/3

145/9ˣ3/-4

145/-12
