Answer:
w=2, -3
Step-by-step explanation:
minus 25 from each side
1+-25+4w^2+4w=25+-25
combine like terms
-24+4w^2+4w=0
factor out the greatest Common factor
4(-6+w+w^2)=0
factor a trinomial
4((-3+-1w)(2+-1w))=0

Answer:(0,4,3i,-3i)
Step-by-step explanation:
x²(x²+9)-4x(x²+9)=0
(x²-4x)(x²+9)=0
x(x-4)=0
x₁=0
x₂=0+4=4
x₃=√-9=3i
x₄=√-9=-3i
