Question

Solve
2x^2+ x + 1 = 0

Answer 1

$\huge{\underline{\underline{\bf Required\: Solution}}}$

By formula method:-

• $\sf p(X) = 2x²+x+1$

here,

• a = 2
• b = 1
• c = 1

Formula of Discriminant:-

$\implies$ $\underline\pink{\boxed{\bf D = b²-4ac}}$

$\implies$ $\sf D = (1)²-4(2)(1)$

$\implies$ $\sf D = 1-8$

$\implies$ $\sf D = -7$

$\implies$ $\sf D>0$

hence this equation has no real roots.
