Question

Find whether the equation has real roots. If real roots exists, find them:                    8x2+2x-12=0​

Answer 1

Answer:

This is an oxidation-reduction (redox) reaction:

4 NV + 4 e- → 4 NIV

(reduction)

2 O-II - 4 e- → 2 O0

(oxidation)

Hg(NO3)2 is an oxidizing agent, Hg(NO3)2 is a reducing agent.

HERE IS UR ANSWER

$_____________________________$

$8 {x}^{2} + 2x - 12 = 0 \\ 4 {x}^{2} + x - 6 = 0 \\ d = {b}^{2} - 2ac \\ = {1}^{2} - 4( - 6)(4) = 1 + 96 = 97 \\ x = \frac{ - b - d}{2a} \: or \: = \frac{- b + d}{2a} \\ = x = \frac{ - 1 - 97}{8} \: and \: x = \frac{ - 1 + 96}{8} \\ x= \frac{ - 98}{8} \: = \frac{49}{4} and \: x = \frac{95}{8}$
