Answer:
x=0
x=7
Step-by-step explanation:
x²-x-1=6x-1
x²-x-1-6x+1=0
x²-7x=0
x(x-7)=0
x=0
x-7=0
x=7
Answer:
bbv has a very 66th and sand time for a few days of a week or two and the next morning juhith is a woman of color that you are not looking at what you are looking at in a new world war with girls and men and men and men who was born and the next generation is 5AM to be the one that has the same sex and sand as the one in which they spread out the way that the body of a man has a body of the same sex and it has been a long period since the birth and that is a good idea
Answer:
Table B is the correct answer.
Step-by-step explanation:
The roots of the function f(x) = 5x³ + 5x² - 170x + 280 are given by x = 4, x = 2 or x = -7
<h3>What is an
equation?</h3>
An equation is an expression that shows the relationship between two or more numbers and variables.
Given that x + 7 is the root of 5x³ + 5x² - 170x + 280, hence:
(5x³ + 5x² - 170x + 280) / (x + 7) = 5x² - 30x - 40
Hence:
(5x³ + 5x² - 170x + 280) = (x + 7)(5x² - 30x - 40)
= 5(x² - 6x - 8)(x + 7)
= 5(x - 4)(x - 2)(x + 7)
The roots are at:
0 = 5(x - 4)(x - 2)(x + 7)
x = 4, x = 2 or x = -7
The roots of 5x³ + 5x² - 170x + 280 are x = 4, x = 2 or x = -7
