Write following equation in standard
form also write the values of
a, b &c.

4z²+7=3z​

Answer 1

Step-by-step explanation:

=> z = 2 – i√7  => z – 2 = –i√7  => (z – 2)2 = (–i√7)2  => z2 – 4z + 4 = –7 => z2 – 4z + 11 = 0. 3z3 – 4z2 + z + 88 = 3z(z2 – 4z + 11) + 8(z2 – 4z + 11)  = 3z(0) + 8(0)  = 0

Answer 2

$\large \green{ \fcolorbox{gray}{black}{ ☑ \: \textbf{Verified \: answer}}}$

4z² + 7 = 3z

4z² - 3z + 7 = 0

4z² - 7z + 4z + 7 = 0

z(4z - 7) + 1(4z + 7) = 0
