Question

a+b = 7 a×b=5
finda²+b²​

Answer 1

Answer:

29. if a+ ib=0 wherei= p −1, then a= b=0 30. if a+ ib= x+ iy,wherei= p −1, then a= xand b= y 31. The roots of the quadratic equationax2+bx+c=0;a6= 0 are −b p b2 −4ac 2a The solution set of the equation is (−b+ p 2a −b− p 2a where = discriminant = b2 −4ac 32.
