Question

if p is a zero of 2x^2-5x+3,then find the value of p

Answer 1

the factors of 3 May be +-1,+-2,+-3
by putting x=1 , we get
2(1)^2 - 5(1)+ 3
2-5+3
5-5
therefore, p= 0

Answer 2

Answer:

The value of p is either 1 or 3/2, here's how;

Step-by-step explanation:

let p(x) = 2x^2 -5x +3

(using the splitting middle term method)

p(x) = 2x^2 -5x +3

p(x) = 2x^2 -2x -3 +3

p(x) = 2x(x-1) -3(x-1)

p(x) = (x-1) (2x-3)

x-1

x = 1

and

2x-3

2x = 3

x = 3/2

thus the zeros of p(x) are 1 and 3/2

hence we can say that the value of p can be either 1 or 3/2
