Try factoring out a 2x from the first 3 terms in the question, like so:

$2x( x^{2} +2x-3)+9$

Now, you can factor the middle quadratic equation and you will have 3 factors plus the constant in the end (the +9). Hope this helps!

Given the equation −4Square root of x minus 3 = 12, solve for x and identify if it is an extraneous solution.

Darina [25.2K]

Answer:

There is no solution for the given radical equation.

x = 225/16 is an extraneous solution.

Step-by-step explanation:

The given equation is

Add 3 to both sides of the equation

Squaring both sides

Divide both sides by 16

Substituting back the value of x in original equation to check the extraneous solution.

Since -18≠ 12. Hence, the value of x does not satisfy the equation.

Therefore, x = 225/16 is an extraneous solution.

tester [92]

Answer:

Step-by-step explanation:

x in (-oo:+oo)

(x/4)/3 = 6 // - 6

(x/4)/3-6 = 0

1/12*x-6 = 0 // + 6

x = 6/1/12

x = 72
