A student solves the following equation and determines that the solution is −2. Is the student correct? Explain. 3 a + 2 − 6a a2
Ganezh [65]

For this case, we have the following equation (according to the comments):

\frac{3}{a+2} - \frac{6a}{a^2-4}  = \frac{1}{a-2}

First, we factor the quadratic expression in the denominator:

\frac{3}{a+2} - \frac{6a}{(a-2)(a+2)}  = \frac{1}{a-2}

Then, we multiply both sides of the equation by (a-2) (a + 2):

\frac{3(a-2)(a+2)}{a+2} - \frac{6a(a-2)(a+2)}{(a-2)(a+2)}  = \frac{(a-2)(a+2)}{a-2}

Later, canceling similar terms we have:

3(a-2) - 6a = a+2

We do distributive property on the left side of the equation:

3a-6-6a=a+2

By grouping variables and constant terms we have:

3a - 6a -a = 2+6

Rewriting we have:

-4a=8

Finally, by clearing "a" we have:

a=-\frac{8}{4} a=-2

Note: the value of a is a extraneous solution because it makes the denominator of the original equation equal to zero.

Answer:

the student correct, but the value of a= -2 is an extraneous solution

Multiply (2m+3)(m^2-2m+2)
Dahasolnce [82]

Answer:

Step-by-step explanation:

The first step is to distribute the 2m and 3 to (m^2-2m+2), like so:

(2m+3)(m^2-2m+2)

2m^3-4m^2+4m+3m^2-6m+6

Then, add like terms:

2m^3 -m^2 -2m + 6

Hii can someone explain to me how to do this? tyvm
Snezhnost [94]

Step-by-step explanation:

it's late but I hope it helps :)

imagine that the > symbol is just an equal sign

so for example

x+2>4

will look like

x+2=4

and you solve normally

×=2

now we bring the symbol back

x>2

but if you multiple or divide by a negative the sign flips

so say you have

-2x>4

make it into

-2x=4

solve

x=-2

but instead of >

you put

x < -2
