Question

If the zero of ployimnomial 2x square plush three x plus alpha is ONE BY 2 find value of alpha the other zero

Answer 1

Step-by-step explanation:

let p(x)=2x^2+3x+alpha

Given that x=1/2.

Therefore;

p(1/2)=2(1/2)^2+3(1/2)+alpha=0

=1/2+3/2+alpha=0

=1+3+2alpha÷2=0

=4+2d=2

=2d=-2

=d=-1.

Therefore, d=-1
