Question

Solve this trinomial
Z^2 + z = -20

Answer 1

your answer is a complex number making your question wrong

Explanation:

First z²+z+20=0, just to make it a quadratic equation, so we can use the quadratric formula:

x=( -b±√b²-4ac)/2a

so to find a b and c we compare

YOUR QUESTION SHOULD BE Z² +Z-20=O.
