Please tell me if this is incorrect. I hope this helps!
To factor quadratic equations of the form ax^2+bx+c=y, you must find two values, j and k, which satisfy two conditions.
jk=ac and j+k=b
The you replace the single linear term bx with jx and kx. Finally then you factor the first pair of terms and the second pair of terms. In this problem...
2k^2-5k-18=0
2k^2+4k-9k-18=0
2k(k+2)-9(k+2)=0
(2k-9)(k+2)=0
so k=-2 and 9/2
k=(-2, 4.5)
Answer: C.It has a negative association
Step-by-step explanation:
-16w-26+9w=-61
-16w+9w=-61+26
-7w=-35
w=5
Least 0.5, 1/4, 0.8, 0.9 greatest
