\[4y^2+8y+7=4\]\[4y^2+8y+7\color{red} { 4 } =4\color{red} { 4 }\]\[4y^2+8y+3=0\]look for the a b c and plug them into the quadratic formula.\[\color{blue} { 4 }y^2+\color{blue} { 8 }y+\color{blue} { 3 }=0\]\[\color{green} { a=4 ~~~~~~~ }\color{green} { b=8 ~~~~~~~ }\color{green} { c=3 ~~~~~~~ }\]

if you haven't learned about imaginary number (I am talking about "i") then simply say no solution. Now, if you have lets go on... \[\huge\color{goldenrod}{ \frac{8±4i \sqrt{3}}{8} }\] and divide top and bottom by 4, \[\huge\color{cornflowerblue}{ \frac{2±i \sqrt{3}}{2} }\]
