One of the roots of the quadratic equation 4mnx^2 – 6m^2x – 6n^2x + 9mn = 0 (m, n ≠ 0) is a)-3m/2n b)3m/2n c)2m/3n d)-2m/3n
maxonik [38]

Answer:

B.\ \frac{3m}{2n}

Step-by-step explanation:

Given

4mnx^2 - 6m^2x - 6n^2x + 9mn = 0\ (m, n \neq  0)

Required

Calculate one of the root of the equation

4mnx^2 - 6m^2x - 6n^2x + 9mn = 0

Factorize

2mx(2nx - 3m) -3n(2nx - 3m) = 0

(2mx - 3n)(2nx - 3m) = 0

Split equation

2mx - 3n = 0\ or\ 2nx - 3m = 0

Make x the subject of formula in both expressions

2mx = 3n\ or\ 2nx = 3m

x = \frac{3n}{2m}\ or\ x = \frac{3m}{2n}

<em>From the list of given options, one of the roots of the equation is</em> \frac{3m}{2n}

PLEASE HELP I GIVE THANKS
ohaa [14]

Take one of the points in the table,

like  x=1  y=5
or    x=2  y=7

Write them into one of the choices on the list,
and see if the result is true.

For example,

-- Take the line in table that says   x=1   y=5.

-- And take the first choice on the list     y = x + 3 .

-- Write '1' in place of 'x', and write '5' in place of 'y'.

-- Then you have    <u>5 = 1 + 3</u> .

Is this true ?  I don't think so.
So the first choice on the list can't be correct.

Try thesame point    x=1   y=5   with  the other choices.
You'll find one that IS correct, and that's the answer.
