Question

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 1

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
