Question

Verify that x=3 is a zero of the polynomial
p(x)=2x3
-5x2
-4x+3.

Answer 1

Hiii friend,


X = 3


P(X) = 2X³-5X²-4X+3


P(3) = 2 × (3)³ - 5 × (3)² - 4 × 3 +3


=> 2 × 27 - 5 × 9 -12 +3


=> 54 -45 - 12 +3


=> 57 -57

=> 0


Remainder is 0 hence 3 is a zero of the given polynomial.

Answer 2

hii friend
here's ur answer hope it helps uuu...

x=3
so now we will fill the value of x in our given polynomial...
we can take the polynomial as
P(x)

so, p(x)=2x^3 -5x^2 - 4x +3

2(3)^3 - 5(3)^2 - 4×3 + 3

2×27 - 5× 9 -12+3

54-45-12+3
57-57
0

hence ,proved
