Question

Find the roots of 4x + 3x + 5 =0 by the method of compleating the square.​

Answer 1

Correct Question

Find the roots of the Equation 4x + 3x + 5 = 0nby the method of completing square.

AnswEr:

$\implies\sf x^2 + \dfrac{3}{4}x + \dfrac{5}{4}$

$\implies\sf x^2 + \dfrac{3}{4}x + \dfrac{3}{8}^{2}$

$\implies\sf\dfrac{-5}{\:\:4} + \dfrac{9}{64}$

$\implies\sf x + \dfrac{3}{8}^{2} = \dfrac{-71}{\:\:64}$

$\implies\sf x + \dfrac{3}{8} = \sqrt{\dfrac{-71}{\:\:64}}$

$\mathsf\red{No,\: real\: roots}$
