Answer:
x^2-4x-12
Step-by-step explanation:
(x-6)(x+2)=x^2-6x+2x-12=x^2-4x-12
Answer:
<h2>
Yes, this is a right triangle.</h2>
Step-by-step explanation:
Hypotenuse always have the highest number than base and perpendicular.
Hypotenuse ( h ) = 15
Base ( b ) = 9
Perpendicular ( p ) = 12
Let's see whether the given triangle is a right triangle or not
Using Pythagoras theorem:

Plugging the values,

Evaluate the power

Calculate the sum

Hypotenuse is equal to the sum of perpendicular and base.
So , we can say that the given lengths of the triangle makes a right triangle.
Hope this helps..
Best regards!!

Answer: n⁴+10n²x+25x²
Step-by-step explanation:
I don;t know how I can use the binomial squares pattern on Brainly, but I can definitely guide you through the problem.
(n²+5x)² [rewrite this from the squared]
(n²+5x)(n²+5x) [use FOIL to expand]
n⁴+5n²x+5n²x+25x² [combine like terms]
n⁴+10n²x+25x²
