If the roots of the equation(b-c)x^2+(c-a)x+(a-b)=0 are equal, thenA)2b=a+c B)a=b=cC)b^2=ac

If the roots of the equation(b-c)x^2+(c-a)x+(a-b)=0 are equal, thenA)2

1.	If the roots of the equation(b-c)x^2+(c-a)x+(a-b)=0 are equal, thenA)2b=a+c B)a=b=cC)b^2=ac
Answer» use (a+b+C)^2 identity Use the formula b²-4ac
