1.
Find the value of the polynomial 5x-4x'+3 at
a) x = 0
b) X = 2
Writo an
+1

Answer 1

Answer:

Putting the value 0 of x.

$5x - 4x + 3$

$5(0) - 4(0) + 3$

$0 - 0 + 3$

$= 3$

Putting the value 2 of x.

$5x - 4x + 3$

$5(2) - 4(2) + 3$

$10 - 8 + 3$

$10 - 11$

$= - 1$

Answer 2

Step-by-step explanation:

The value of a polynomial p(x) at x= a(let) is denoted by p(a).

Solution:

i)                  

p(x) = 5x - 4x² + 3On putting x=0 ,

p(0) = 5(0) - 4(0)² + 3

= 0 - 0 +3=3

= 3

ii)

(x) = 5x - 4x² + 3

On putting x= -1,

p(-1) = 5(-1) - 4(-1)²+ 3

= -5 - 4(1) + 3

= -5-4+3= -9+3= -6

=-6

iii)

p(x) = 5x - 4x² + 3

On putting x=2

p(2) = 5(2) - 4(2)² + 3

= 10 – 16 + 3 = -6+3

= -3

hope it helps
