Discriminant of 9x2 + 2 = 10x? –356 –172 28 72

Discriminant of 9x² + 2 = 10x is:

28

Step-by-step explanation:

Discriminant(D) of a equation ax²+bx+c=0 is:

D=b²-4ac

We are given a polynomial equation:

9x² + 2 = 10x

i.e. 9x²-10x+2=0

a=9,b= -10 and c=2

D=(-10)²-4×9×2

 = 100-72

 =28

Hence, discriminant of 9x² + 2 = 10x is:

28
