Question

2)х^4-14х^2-32=0

3)х^4+3х^2-28=0

4)х^4-4х^2-45=0

Answer 1

x^4-14*x^2-32=0

y=x^2

y^2-14*y-32=0

D=14^2-4*1*(-32)=324

324^0.5=18

y=(14+18)/(2*1)=16

x=16^0.5=4

y=16
y=x^2
x=y^0.5
x=16^0.5=4

Answer 2

х^4+3*х^2-28=0

y=x^2

y^2+3*y-28=0

D=3^2-4*1*(-28)=121

121^0.5=11

y=(3-11)/(2*1)=4

x=4^0.5=2

Answer 3

х^4-4*х^2-45=0

y=x^2

y^2-4*y-45=0

D=4^2-4*1*(-45)=196

196^0.5=14

y=(4+14)/(2*1)=9

x=9^0.5=3
