Y = x2 + 4x + 11OK. That's very interesting.Is there a question ?
If the 64 has a minus sign, then the solution is x = +/-5 Simplifying gives 4x squared = 100 ie x squared = 25...
It has two equal solutions of 2
Just the one solution.
x = -½
y=xsquared-4x+2
The discriminant is 121.

Y = x squared -4x plus 3 is an equation of a function. It is neither called a domain nor a range.

Just the one solution.
X=1/2
Two solutions and they are:- x = 0 and y = 3
It equals 53X- a number is squared when it is multiplied by itself, so 7X by 7X = 49X. 2X by 2X =4X, so 49X + 4X is 53X.
