Answer:
x^2+10x+25 is a polynomial
Step-by-step explanation:
A polynomial is an expression with exponets such as x^2 therefore your eqation that will become x^2+10x+25 is always a polynomial
Assuming you meant (x+5)^2
You need to find the prime factors of each term in order to find the greatest common factor.
The answer is 3.
Answer:
D) x=5, x=-5.
Step-by-step explanation:
x^2-25=0
factor
(x+5)(x-5)=0
x+5=0, x-5=0,
x=0-5=-5,
x=0+5=5.
Answer:
x=1, y=1. (1, 1). The answer is D).
Step-by-step explanation:
3x-5y=-2
4x-7y=-3
--------------
4(3x-5y)=4(-2)
-3(4x-7y)=-3(-3)
------------------------
12x-20y=-8
-12x+21y=9
--------------------
y=1
3x-5(1)=-2
3x-5=-2
3x=-2+5
3x=3
x=3/3
x=1
