Question

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

Answer 1

I hope this helps you

Answer 2

Discriminant of 9x² + 2 = 10x is:

28

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
