Question

Show that 2 is a zero of the polynomial 2x^2-5x+2

Answer 1

= 2x²-5x+ 2
= 2x²-4x-x+2
= 2x(x-2)-1(x-2)
= (2x-1)(x-2)
= x = 1/2,2
hence , 2 is a zero of 2x²-5x+2

Hope This Helps....

Answer 2

p(x)=2x²-5x+2

p(2)= 2(2)²-5(2)+2
= 8-10+2
= 0

Hence, 2 is the zero of this polymial.

Hope it helps
