{ int a,b; { a=a^2; } { b=b^2; } { c=a^2+b^2+2*a*b; print f("%d%d%d",&c); get ch(); } ]
d = 2
-d + 2 = 5(- 2 from both sides)-d = 3(x both sides by -1)d = -3
d/dx(x + 2) = d/dx(x) + d/dx(2) = 1 + 0 = 1

D = b²-4ac a=2, b=5, c=4 D=5²-4(2*4) D=25-4(8) D=25-32 D=-7■
It has 4 d electrons.
In terms of variables, a ± d would be (a + d) or (a - d) Example: if a = 1, and d = 2, then a ± d = 3 and a ± d = -1
15+d^2=96 d^2=96-15=81 so d=9 or d = -9
int a=2, b=3, c=4, d=5; printf ("%d/%d + %d/%d = %d/%d\n", a, b, c, d, a*d+b*c, b*d);
