Question

if one zero of the quadratic polynomial 2z^2-3x+p is 3,find its other zero .Also find the value of p

Answer 1

Step-by-step explanation:

Q(x)=2x2-3x+p

q(3)=2×(3)^2-3×3+p

0 =2×9-9+p

0 =18-9+p

0 =9+p

p =-9

q(x)=2x2-3x+p

q(x)=2x2-3x-9

=2x2-(6-3)x-9

=2x2-6x+3x-9

=2x(x-3)+3(x-3)

=(2x+3)(x-3)

x=-3/2,3
