Question

find the zeros of the polynomial 4z²-1​

Answer 1

Step-by-step explanation:

Given  P(z)=4z2−15πz−4π2

To find out its roots, we have to equate it to zero

4z2−15πz−4π2=0

4z2−16πz+πz−4π2=0

4z(z−4π)+π(z−4π)=0

(4z+π)(z−4π)=0

z=4π,−4π

I Hope you understood

Answer 2

⋆ ANSWER ⋆

━━━━━━━━━━━━━━━━━━

= 4z²-1 = 0

= 4z²= 1

= z² = ¼

= z = √¼
