Question

Discriminant of x^2 + 2x + 4 = 0 is.​

Answer 1

$\Huge{\textbf{\textsf{{\color{navy}{an}}{\purple{sw}}{\pink{er}}{\color{pink}{:}}}}}$

$\large\bf{{\underline{Quadratic~equation}}:}$

$\sf{~~~~~~~~~~~x^{2}+2x+4=0}$

$\bf{Here;}$

$\sf{~~~~~~~~~~~a=1~,~~b=2~,~~c=4}$

$\bf{Discriminant:}$

$\sf{~~~~~~~~~~~b^{2}-4ac}$

$\sf{: \implies (2)^{2}-4(1)(4)}$

$\sf{: \implies (4)-4(4)}$

$\sf{: \implies 4-16}$

$\sf{: \implies \color{red}{\underline{\boxed{\bf -12}}}}$

$\large\bf\therefore{{\underline{Discriminant}}:}$

$\large\bf\color{red}{~~~~~~~~~~~~~~{\underline{\underline{-12}}}~~~~~~~~~~{\huge{✓}}}$

Answer 2

Answer:

Question:–

$1) \: x²+2x+4=0$

Let,

☞ a = 1, b = 2, c = 4

Discriminate:-

➪ b²- 4ac

➪ (2)² - 4(1)(4)

➪ 4 - 16

➪ -12

So the discriminate is -12
