4=q2+7
We move all terms to the left:
4-(q2+7)=0
We add all the numbers together, and all the variables
-(+q^2+7)+4=0
We get rid of parentheses
-q^2-7+4=0
We add all the numbers together, and all the variables
-1q^2-3=0
a = -1; b = 0; c = -3;
Δ = b2-4ac
Δ = 02-4·(-1)·(-3)
Δ = -12
Delta is less than zero, so there is no solution for the equation
