3a^3..........................
Answer:
none
Step-by-step explanation:
y=x²+1
y=x
x²+1=x
x²-x+1=0
Disc.=b²-4ac=(-1)²-4×1×1=1-4=-3<0
so roots are imaginary.
Answer:
y = 
Step-by-step explanation:
Given
x(y + 2) = 3x + y ← distribute parenthesis on left side
xy + 2x = 3x + y ( subtract 2x from both sides )
xy = x + y ( subtract y from both sides )
xy - y = x ← factor out y from each term on the left side )
y(x - 1) = x ← divide both sides by (x - 1)
y = 
I hope this helps ( there is no negatives )
