What is true about the solution above.
Masja [62]

ANSWER

x =  \pm \sqrt{3}

and they are actual solutions.

EXPLANATION

The given equation is:

\frac{ {x}^{2} }{2x - 6}  =  \frac{9}{6x - 18}

Cross multiply

{x}^{2} (6x - 18) = 9(2x -6 )

This implies;

{x}^{2} (6x - 18) - 9(2x - 6) = 0

3{x}^{2} (2x - 6) - 9(2x - 6) = 0

Factor

(3 {x}^{2}  - 9)(2x - 6) = 0

3 {x}^{2}  - 9 = 0 \: or \: 2x - 6= 0

3 {x}^{2}   = 9 \: or \: 2x  = 6

{x}^{2}   = 3\: or \: x  = 3

{x}  =  \pm \sqrt{3} \: or \: x  = 3

The domain of the given equation is

x \ne3

Therefore the actual solutions are

x =  \pm \sqrt{3}

NB: x=3 is not in the domain of the given equation. It cannot be an extraneous solution.

For the equation 3(7 + x) = 3x + k, which value of k will create an equation with Infinity many solutions a) 7 b) 21 c) 10 d) 3
Svet_ta [14]

Answer:

21

Step-by-step explanation:

We have to create an identity

3x + 21 = 3x + k

if we substitute k with 21 we have

3x + 21 = 3x + 21

that is an identity so it’s true for every value of x
