Answer:
y=[tex]-\frac{\sqrt[3]{63} }{3}[/tex]
y=0
Step-by-step explanation:
−
4
[tex]y^{2}[/tex]
(
3
[tex]y^{3}[/tex]
+
7
)
-4[tex]y^{2}[/tex]
=0,
(
3
[tex]y^{3}[/tex]
+
7
)=0
[tex]y^{2}[/tex]
=0 3[tex]y^{3}[/tex]
=-7
y=0 [tex]y^{3}[/tex]
=[tex]\frac{-7}{3}[/tex]
y=[tex]-\frac{\sqrt[3]{63} }{3}[/tex]
