Question

find out the discriminant of the given quadratic equation​

Answer 1

Answer:

discriminant(∆)=bsquare (b2)- 4ac

=8-4x-6x1= 8+24=32

✒ Tᴏ Fɪɴᴅ :

↪ Discriminant of the given equation

▂▂▂▂▂▂▂▂▂▂▂▂▂▂▂▂▂▂▂▂▂▂

✿ Fᴏʀᴍᴜʟᴀ ᴛᴏ ʙᴇ ᴜsᴇᴅ :

➳ D = B² - 4AC

▂▂▂▂▂▂▂▂▂▂▂▂▂▂▂▂▂▂▂▂▂▂

☯ Sᴏʟᴜᴛɪᴏɴ :

→ D = B² - 4AC

→ D = (2√2)² - 4 × 1 × (-6)

→ D = 4 × 2 + 24

→ D = 8 + 24

→ D = 34

Important properties of discriminant

⇒ If √b²-4ac = 0, then there is exactly one real solution.

⇒ If √b²-4ac ≻ 0, then there are exactly two real solutions.

⇒ If √b²-4ac ≺ 0, there are exactly two imaginary solutions.
