Not sure:((((((( sorrryyyy
Idk what the answer is to your question
Answer:
12m^2 - 9m -30
Step-by-step explanation:
So rewrite the equation to this:
4m * 3m
4m * -6
5 * 3m
5 * -6
Now solve:
4m * 3m = 12m^2
4m * -6 = -24m
5 * 3m = 15m
5 * -6 = -30
Now add them together in order:
12m^2 - 24m + 15m - 30
Simplify -24m and 15m:
12m^2 - 9m -30
Thus
12m^2 - 9m -30 is the answer
Hope this helps!
3) y^2 - 1 = 24
add 1 to each side:
y^2 = 25
Take square root of each side: y = √25
y = 5 or -5
4) y^2 - 1 =48
Add 1 to each side:
y^2 = 49
Take square root of each side:
y = 7 or -7
Hello there.
First, assume the numbers
such that they satisties both affirmations:
- The sum of the squares of two numbers is
. - The product of the two numbers is
.
With these informations, we can set the following equations:

Multiply both sides of the second equation by a factor of
:

Make 

We can rewrite the expression on the left hand side using the binomial expansion in reverse:
, such that:

The square of a number is equal to
if and only if such number is equal to
, thus:

Substituting that information from
in
, we get:

Calculate the square root on both sides of the equation:

Once again with the information in
, we have that:

The set of solutions of that satisfies both affirmations is:

This is the set we were looking for.
