Question

Let p(x)=2x^2+5x-3 check weather 1/2is a zero of the polynomial p(x)

Answer 1

$\huge\bold\color{red}{answer}$

$= > 2( \frac{1}{2} ) {}^{2} + 5 \times \frac{1}{2} -3$

$= > \frac{1}{2} + \frac{5}{2} - 3$

$= > \frac{1 + 5 - 6}{2}$

$= > 0$

YES... 1/2 IS ZERO OF POLYNOMIAL

HOPE ITS HELPFUL.....:-)

Answer 2

Answer:

g(x) = 1/2

x = 1/2

By putting the value of x in p(x), we get

p(1/2) = 2 × (1/2)^2 + 5 × (1/2) - 3

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

= (6/2) - (3/1)

By taking the LCM of both denominators

= 6/2 - 6/2

= 0

Hence, the remainder is 0 so, 1/2 is the zero of the polynomial p(x).
