What is the answer to Factor 3a^2-6a

Anton [14]

Hi there!

$3 {a}^{2} - 6a \: = 3a(a - 2)$

We can see this by writing the factors as multipliers. We get the following:
$3a {}^{2} = 3 \times \: a \times a$
$6a = 3 \times 2 \times a$

Now we can see that the terms that are in common are 3 and a, and therefore we can bring those outside the parenthesis.

Are 4/16 and 0.25/2 equivalent numbers? If so, explain how they are.

Aleksandr-060686 [28]

Two fractions are equivalent if the product of the numerator of the first and the denominator of the second is equal to the product of the numerator of the second and the denominator of the first.
4 x 2 ___ 16 x 0.25
8 is not equal to 4
Thus, they are not equivalent.

Find the solution of 3 times the square root of the quantity of x plus 6 equals negative 12, and determine if it is an extraneou

Anna35 [415]

For this case we have the following equation:
$3 \sqrt{x+6}=-12$
Rewriting we have:
$\sqrt{x+6}= \frac{-12}{3}$
$\sqrt{x+6}=-4$
We raise both members of the equation to the square:
$(\sqrt{x+6})^2=(-4)^2$
Rewriting we have:
$x+6=16$
$x=16-6$
$x=10$
It's a extraneous solution because equality is not met by substituting x = 10 in the original equation:
$3 \sqrt{10+6}=-12$
$3 \sqrt{16}=-12$
$3(4)=-12$
$12=-12$
Answer:
The solution is:
$x=10$
It's a extraneous solution
