Question

the zeros of polynomial 4 x square - 2 X + 9​

Answer 1

Here's your answer mate:-

4x^2-2x+9

It's a quadratic equation

therefore:-

f(x)=0

4x^2-2x+9=0

a=4,b=-2,c=9

quadratic formula:-

x=-b±√(b^2-4ac)/2a

x=2±√2^2-4*4*9/2*4

x=2±√4-144/8

x=2±√140/8

x=2± 2√35/8

x=1±√35/4

x=1+√35/4,x=1-√35/4
