Which of the following is an extraneous solution of (45-3x)^1/2=x-9?
Iteru [2.4K]

Answer:

C. x =3

Step-by-step explanation:

Extraneous solution is that root of a transformed equation that doesn't satisfy the equation in it's original form because it was excluded from the domain of the original equation.

Let's solve the equation first

\sqrt{45-3x} = x-9\\Taking\ square\ on\ both\ sides\\{(\sqrt{45-3x})}^2 = {(x-9)}^2\\45-3x = x^2-18x+81\\0 = x^2-18x+81-45+3x\\x^2-15x+36 = 0\\x^2-12x-3x+36 = 0\\x(x-12)-3(x-12) = 0\\(x-3)(x-12)\\x-3 = 0\\=> x =3\\x-12 = 0\\x = 12\\We\ will\ check\ the\ solutions\ one\ by\ one\\So,\\for\ x=3\\\sqrt{45-3(3)} = 3-9\\\sqrt{45-9} = -6\\\sqrt{36}= -6\\6\neq -6\\For x=12\\\sqrt{45-3(12)} = 12-9\\\sqrt{45-36} = 6\\\sqrt{36}= 6\\6=6

Hence, we can conclude that x=3 is an extraneous solution of the equation ..

Solve the equation for x. the square root of the quantity x minus 8 end quantity plus 2 equals 7 x = 1 x = 13 x = 17 x = 33
Masteriza [31]

The solution of the equation (√x-8) + 2 = 7 is x = 13.

According to the given question.

We have an equation

\sqrt{x - 8} + 2 = 7x

Since, we solve the above equation for x .

Therefore,

\sqrt{x - 8} + 2 = 7

⇒ (√x - 8) = 7 - 2

⇒ (√x - 8) = 5

Squarring both the sides.

⇒ x - 8 = 5

⇒ x = 5 + 8

⇒ x = 13

Hence, the solution of the equation (√x-8) + 2 = 7 is x = 13.
