If you would like to write x^4y - 4x^2y - 5y in a completely factored form, you can do this using the following steps:
x^4y - 4x^2y - 5y = y * (x^4 - 4x^2 - 5) = y * (x^2 + 1) * (x^2 - 5)
The correct result would be <span>y * (x^2 + 1) * (x^2 - 5).</span>
Answer:
u=-1
Step-by-step explanation:
-3|2-4u|+5<-13
-6+12u+5<-13
12u<-13-5+6
12u<-12
12u/12<-12/12
u=-1
<span>The system of the equations has no solution; the two lines are parallel.</span>
Answer:
5 must be added to both the terms to get the ratio 4:5.
Step-by-step explanation:
(3+x)/(5+x)=4/5
Therefore,
15+5x=20+4x
=5x-4x=20-15
=x=5
