Answer:
both negative
Step-by-step explanation:
Descartes rule of signs tells us how many positive and negative real roots a polynomial has.
Given
f(x) = x² + 5x + 6 , with signs
+, +, + ← no change of signs, thus no positive zeros
f(- x) = (- x)² + 5(- x) + 6 = x² - 5x + 6 , with signs
+, -, + ← with 2 changes of signs. thus 2 negative zeros
The answer is B because you must multiply 135 by 9 to get the answer of the tree
Answer:
y=1.5x+5
Step-by-step explanation:
Step-by-step explanation:
6^3+6^2=216+36=252
25^2=625
hope that helps :)
You can use synthetic division to find the other factor, or you can simply divide the leading and trailing terms by the numbers you have. (This works if the binomial you have is truly a factor of the trinomial, which it is.)
2g²/2g = g
140/14 = 10
Your other factor (the length) is g+10.
(2g² +34g +140) = (2g +14)*(g +10)
