Question

28/9+2m/3-3=0.find the value of m​

Answer 1

Answer:

x2 – 5x + 6 = 0; 2, -3

Let us substitute the given values in the expression and check,

When, x = 2

x2 – 5x + 6 = 0

(2)2 – 5(2) + 6 = 0

4 – 10 + 6 = 0

0 = 0

∴ x = 0

When, x = -3

x2 – 5x + 6 = 0

(-3)2 – 5(-3) + 6 = 0

9 + 15 + 6 = 0

30 = 0

∴ x ≠ 0

Hence, the value x = 2 is the root of the equation.

And value x = -3 is not a root of the equation.

Step-by-step explanation:

Answer 2

$\frac{28}{ 9} + \frac{2m}{3} - 3 = 0 \\ \\ \frac{28 + 6m - 9}{9} = 0 \\ \\ \frac{19 + 6m}{9} = 0 \\ \\ 19 + 6m = 0 \\ 6m = - 19 \\ m = \frac{ - 19}{6}$
