Please help and explain calculaions

[2 points] Calculate and compare results using both equation pairs (x1, x2) and (xos, XB) using D = 5, C = 12, B = 3. Are the results the same? General equations: a = 3(5), b = 2(12), and c = 3 a = 15, b = 24, and c = 3 -b-1b2-4ac X2 =- - za x = b+Vb2-4a za Transformed equations: D = 5, C = 12, and B = 3 X1 = -c+VC2-3DB' X2 -C-VC2-3DB
