Question

write three quadratic polynomials that have no zeroes
​

Answer 1

Answer:

A quadratic polynomial ax

2

+bx+c=0 has no solution when D=b

2

−4ac<0

These quadratic polynomials have no zeroes

y=2x

2

−4x+5⇒D=(−4)

2

−4(2)(5)=16−40=−24

y=2x−3x

2

+2⇒D=(−3)

2

−4(2)(2)=−7

y=x

2

−2x+4⇒D=(−2)

2

−4(1)(4)=−12

Answer 2

these they won't have zeroes

1)y=2x²-4+5

D=-4²-4(2)(5)

=16-40

=-24

2)y=2x-3x²+2

D=-3²-4(2)(2)

=-7

3)y=x²-2x+4

D=-2²-4(1)(4)=-12

Hope this helps you to...
