Answer:
Step-by-step explanation:
remember the rules of dividing the same base with different powers,
4^5/4^3=
=4^2
Answer:
2 and 8 (other people already answered so i might be of no help, sorry)
For
y=ax²+bx+c
the x value of the axis of symmetry is -b/(2a)
so test them
A., -b/(2a)=-(-8)/(2*-2)=8/-4=-2, yep
B. -b/(2a)=-2/(2*1/2)=-2/1=-2, yep
C. -b/(2a)=-(-16)/(2*4)=16/8=2, nope, need -2
D. -b/(2a)=-12/(2*3)=-12/6=-2, yep
answer is C
<span>2x + x</span>²<span> + 3x + 5x</span>²<span> - 10x (combine like terms)
6x</span>² + 5x -10x
6x² - 5x
which is the same as
-5x +6x²
Your answer is C
Answer:
Options A) and E)
Step-by-step explanation:
If you use Ruffini's method for polynomials, you can find the roots.
The given picture shows us the first root of the polynomial
wich is 2.
Thus, the original polynomial can be written as

Here, you can notice that (x-2) is a factor
