Question

Show that the polynomials given below have no zeroes
14. x2 + 2x + 3
15. y2 - 6y + 12​

Answer 1

Answer:

Step-by-step explanation:

x²+2x+3

b=2 and c = 3 and a=1

D= b²-4ac

  = 2²-4x1x3

  = 4-12

  =-8

this shows that there is no zeros

--------------------------------------------------------------------

y²-6y+12

a=1 and b=-6 and c =12

D=b²-4ac

  = (-6)²-4x1x12

  = -36-36

  = -72

they have no zeros
