Answer 2

Answer:

(i) 3 (ii) 12 (iii) 9 (iv) 3/2

Step-by-step explanation:

put value of x in polynomial 4x2 - 5x+3

y=4x2 - 5x+3

i)x=0

y=0-0+3=3

ii)x=-1

y=4×(-1)×(-1)-5×(-1)+3

=4+5+3

=12

iii)x=2

y=4×(2)×(2) -5×(2) +3

=16-10+3

=9

iv)x=1/2

y=4×(1/2)×(1/2)-5×(1/2)+3

=1-5/2+3

=4-5/2 or 8/2-5/2

=3/2
