Answer:
Step-by-step explanation:
Since this is a 4th degree polynomial, 2 of the roots will not be real. Finding them is next to impossible off a calculator until the real ones are found first. That's simple enough process.
and
Divide both sides by 5:
Rewrite to get
which simplifies down to
Taking the square root of both sides gives you the real roots of x = 2 and -2.
That leaves you with 2 roots that are imaginary. After you factor out the 2 and the -2 by synthetic division, you are left with the depressed quadratic
Factor out the 5:
So the final answer is D.
Answer:
Graph
Step-by-step explanation:
Answer:
the perimeter of the rectangle = 2(length + width)
= 2(4x^2 + 2 feet + 5x^2 + 3x feet )
= 2(4x^2 + 5x^2 + 2+ 3x)feet
= 2(x^2(4+5) + 2+ 3x) feet
= 2(9x^2 + 3x + 2)feet
= 18x^2 + 6x +4 feet
