Question

Show that 1/2 is a zero of the polynomial

p(x) = 2x2 + 7x-
4.​

Answer 1

Answer:

Therefore, 1/2 is not zero of p(x)=2×2+7x-4

Step-by-step explanation:

p(x)=2×2+7x-4

x=1/2

p(1/2)=2×2+7(1/2)-4

p(1/2)=4+7×1-2

p(1/2)=4+7-2

p(1/2)=11-2

p(1/2)=9

Therefore,1/2 is not zero of polynomial
