Question

What is the discriminant of 9x2 + 2 = 10x?

Answer 1

I hope this helps you



ax^2+bx+c=0



disctirminant =b^2-4ac



9x^2-10x+2=0



a=9 b= -10 c=2



disctirminant = (-10)^2-4.9.2


disctirminant = 100-72


disctirminant = 28


x1= -(-10)+square root of28/2.9


x1=5+ square root of 7/9


x2= 5- square root of 7/9

Answer 2
