Question

find the value of polynomials p(x)=2x square - 5x + 3​

Answer 1

Answer:

1

Step-by-step explanation:

Answer 2

Answer:

x = 1, 1/2

Step-by-step explanation:

$p(x)=2x^2-5x+3\\p(x) = 2x^2 -6x+1x+3\\p(x) = 2x(x-3)-1(x-3)\\p(x) = (x-3)*(2x-1)$

from here, we can calculate its roots, which are-

case 1-

$p(1) = (1-1)(2*1-1)\\p(1) = (1-1)(2-1) = 0(1) = 0$

case 2-

$p(1/2) = ((1/2)-1)((2*1/2)-1)\\p(1/2) = (-1/2)(1-1)\\p(1/2) = (-1/2)(0)=0$

therefore, x can either be 1 or 1/2
