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]
