Question

EXERCISE -- 2.2
1. Find the value of the polynomial 4x2 - 5x+3, at
(i).r=0
(ii) r=-1
).
(iii)x=2​

Answer 1

Answer:

Step-by-step explanation:

Let p(x)=4x² - 5x+3

(i) x=0

p(0)=4*0²-5*0+3=3

(ii) x=-1

p(-1)=4*(-1)²-5(-1)+3

=4*1+5+3

=4+5+3=12

(iii) x=2

p(2)=4*(2)²-5*2+3=4*4-10+3=9

Answer 2

Answer:

1). 3

2). 12

3). 9
