How can i evaluate the 2nd equation in this program? I tried some and it doesnt show the value

Here i got the 3 equations but i want to evaluate the equations with values of x , what code should i add?

For example in the 2nd eqauation i want to evaluate it when x=5.333

%% Quadratic Spline Method
x = [0 5 7 8 10];
y = [0 2 -1 -2 20];

syms a1 a2 a3 b1 b2 b3 c1 c2 c3 x1 x2 x3 x4 x5 x6 x7 x8
a1 = 0;

x1 = a1*x(2)^2+b1*x(2)+c1 == y(2);
x2 = a2*x(2)^2+b2*x(2)+c2 == y(2);

x3 = a2*x(3)^2+b2*x(3)+c2 == y(3);
x4 = a3*x(3)^2+b3*x(3)+c3 == y(3);

x5 = 2*a2*x(2)+b2 == 2*a1*x(2)+b1;
x6 = 2*a3*x(3)+b3 == 2*a2*x(3)+b2;

x7 = a1*x(1)^2+b1*x(1)+c1 == y(1); 
x8 = a3*x(4)^2+b3*x(4)+c3 == y(4);


m1 = [0 x(2) 1;0 x(1) 1 ];
s1 = [y(2) y(1)]';
d1 = m1\s1;
a1 = d1(1);
b1 = d1(2);
c1 = d1(3);


m2 = [2*x(2) 1 0; x(2)^2 x(2) 1; x(3)^2 x(3) 1];
s2 = [2*a1*x(2)+b1 y(2) y(3)]';
d2 = m2\s2;
a2 = d2(1);
b2 = d2(2);
c2 = d2(3);


m3 = [x(3)^2 x(3) 1;x(4)^2 x(4) 1; 2*x(3) 1 0];
s3 = [y(3) y(4) 2*a2*x(3)+b2]';
d3 = m3\s3;
a3 = d3(1);
b3 = d3(2);
c3 = d3(3);

syms x
disp("equation for the first sub-interval is");
e1 = a1*x^2+b1*x+c1 == 0;
disp(e1);
disp("equation for the second sub-interval is");
e2 = a2*x^2+b2*x+c2 == 0;
disp(e2);
disp("equation for the third sub-interval is");
e3 = a3*x^2+b3*x+c3 == 0;
disp(e3);

these are the results , but i want to evaluate each at some values of x

equation for the first sub-interval is

(2*x)/5 == 0

equation for the second sub-interval is

(99*x)/10 - (19*x^2)/20 - 95/4 == 0

equation for the third sub-interval is

(12*x^2)/5 - 37*x + 702/5 == 0

Which one is "the 2nd equation"?

[Miku]

the (e2) sir ,2nd sub interval

(99*x)/10 - (19*x^2)/20 - 95/4 == 0 , i want to evaluate this without creating new script
