Question

find the value of polynomial 4x²-5x+3 when x=-1 & x= ½​

Answer 1

Answer:

Let p(x) = 4x² - 5x + 3

If x = 1/2

Value of p(1/2)

= 4(1/2)² - 5(1/2) + 3

= 4/4 - 5/2 + 3

= 1 - 5/2 + 3

= 4 - 5/2

= 4 - 2.5

= 1.5

Or

p(x) = 3/2

Answer 2

Step-by-step explanation:

when x = -1

f(x) = 4(1)-5(-1)+3

= 4+5+3 = 12

when x = 1/2

f(x) = 4(1/4) - 5(1/2) +3

= 1-5/2+3 = 3/2
