The number that needs to be added to the equation [tex]x^{2} +4x+3[/tex] will be 1
What number of tiles is needed to make the equation perfect square?
Given equation is [tex]x^{2} +4x+3[/tex]
Now by adding 1 to the equation [tex]x^{2} +4x+3[/tex] we get
[tex]x^{2} +4x+3+1=x^{2} +4x+4[/tex]
[tex]x^{2} +2x+2x+4[/tex]
Now by splitting the equation
[tex]x(x+2)+2(x+2)[/tex]
[tex](x+2)(x+2)[/tex]
[tex](x+2)^{2}[/tex]
Thus the number that needs to be added to the equation [tex]x^{2} +4x+3[/tex] will be 1
