Question

If 1 and 2 are the roots of 3x^2-2mx+2n=0 find the value of M and n

Answer 1

Step-by-step explanation:

$\huge\underline{\underline{\sf ANSWER}} \\ if \: 2 \: and \: 1 \: are \: roots = > \\ 2 + 1 = \frac{ - b}{a} = - \frac{ - 2m}{3 } \\ 3 = - ( - \frac{2m}{3} ) \\ m = \frac{ 9}{2} \\ \\ 2 \times 1 = \frac{c}{a} = \frac{2n}{3} \\ 2 = \frac{2n}{3} \\ n = 3$
