Getting fprintf to display two different outputs from a function on the same line.

function [xVertex,yVertex] = PolyVertex(a, b, c)
%PolyVertex comoute the X and Y vertex of any polynomial given a, b, and c.
% Get a, b and c from y = ax^2 + bx + c and plug them in to get the x and y vertex
xVertrex = -(b/(2*a));
yVertex = (a*(xVertex^2)) + (b*xVertex) + c
end


% initialize a, b, and c
a = 3;
b = -6;
c = 4;
% call your function
%   assign both outputs
PolyVertex(a, b, c);

% call fprintf to display the results in a single line
%   use %d as the placeholder
%   include descriptive text
fprintf("The X vertex is %d The Y vertex is %d " PolyVertex(a, b, c)) 

I'm having trouble getting the last line to print xVertex and yVertex.

% initialize a, b, and c
a = 3;
b = -6;
c = 4;
% call PolyVertex and assign both outputs
[xV,yV] = PolyVertex(a, b, c);
% display the result
fprintf("The X vertex is %d The Y vertex is %d ", xV, yV) 

The X vertex is 1 The Y vertex is 1 

function [xVertex,yVertex] = PolyVertex(a, b, c)
%PolyVertex comoute the X and Y vertex of any polynomial given a, b, and c.
% Get a, b and c from y = ax^2 + bx + c and plug them in to get the x and y vertex
% xVertrex = -(b/(2*a)); % fixed typo "xVertrex"
xVertex = -(b/(2*a));
yVertex = (a*(xVertex^2)) + (b*xVertex) + c;
end

Ohhh thank you so much that makes so much sense!
