Question

2 x power 2 + 11 x + 42
Factorize it......

Answer 1

Hey there !

Thanks for the Question !

Here's the Answer !

Equation : 2x² + 11 x + 42 = 0

Applying method of Quadratic Formula:

$Quadratic \ Formula = \frac{ - b \pm \sqrt{ b^2 - 4 ac} }{ 2a } \\\\ Here \ 'a' \ represents \ 2, \ 'b '\ represents \ 11 \ and \ 'c' \ represents \ 42$

Discriminant :

$b^2 - 4ac = 11^2 - 4 \times 2 \times 42 \\\\ b^2 - 4ac = 121 - 336 = -215$

Since the discriminant is less than zero, the equation has only imaginary roots. Hence the equation cannot have real roots.

Hope my answer helped !
