Answer 1

$⇶ \tt\green{Correct\: Question}$

solve the following equation by using

quadratic formula.

$5 {z}^{2} - 17z - 12 = 0$

$⇶ \tt\red{Answer}$

$5 {z}^{2} - 17z - 12 = 0$

$↣ - B \frac{ + - \sqrt{ {B}^{2} - 4 \times A \times C } }{2 \times A }$

$↣ - ( - 17) \frac{ + - \sqrt{ { - 17}^{2} - 4 \times 5 \times - 12 } }{2 \times 5 }$

$↣ 17 \frac{ + - \sqrt{ 289- - 240} }{10 }$

$↣ \frac{ 17+ - \sqrt{ 529} }{10 }$

$↣ \frac{ 17+ - 23 }{10 }$

$Plus \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: minus \\ z = \frac{(17 + 23)}{10} \: \: \: \: z = \frac{(17 - 23)}{10 } \\ z = \frac{40}{10} \: \: \: \: \: \: \: \: \: z = \frac{ - 6}{10} \\ x = (4) \: \: \: \: \: \: x = ( \frac{ - 3}{5} ) \\ x = 4 \: \: \: \: \: x = - 0.6$

Answer 2

Answer:

to solve a quadratic formula we will be needed at least two quadratic equations or square containing equations. this can't be whole question
