if m and n are the zeros of the polynomial 3x square + 11 x minus 4 find the value of m by n plus n by m​

Answer»

Answer:

1

Step-by-step explanation:

Eq = 3x^{2} +11x-4

DISCRIMINANT= b^{2}-4ac

a= 3 b= 11 c= -4

D= 121 +48

=169

roots are -3/2, 17/6

-b±\sqrt{b^{2}-4ac } /2a

=4±\sqrt{169}/6

=4±13/6

So m = 17/6 N = -3/2

m/n= 17/6 * -2/3                    n/m= -3/2 * 6/17

=   -17/9                                        = -9/17

\frac{m}{n} + \frac{n}{m} = 1
