Question

I need help on this can you help me? Complete the squarex^2+4x+3=0

Answer 1

The given quadratic equation is,

`x^2+4x+3=0`

Here, the coeficients are,

`\begin{gathered} a=1 \\ b=4 \\ c=3 \end{gathered}`

Consider the quadratic equation and to complete the square we have the condition,

`\begin{gathered} d=(b)/(2a)=(4)/(2)=2 \\ e=c-(b^2)/(4a) \end{gathered}`
