solving and simplifying the polynomial in standard form


∵ 


We know that standard form means that the terms of the expression are ordered from biggest exponent to lowest exponent.
Thus, a simplified polynomial in standard form is:

Answer:
I believe the top one is true! I'm sorry I couldn't answer them all :c
Step-by-step explanation:
A<span> system of linear equations</span><span> means two or more linear equations.
</span>A system of two linear equations has an infinite number of solutions is the rarest case and it only happens when both the lines are same.
For example,
y = 3x+1 and 4y = 12x +8
These lines will have infinite number of solutions.
Hence,
The best answer is :
<span>B) The two equations are the same line.</span>
