Question

What is the discriminat of 9x²+2=10x

Answer 1

Answer: 28

Explanation:

The discriminant in the quadratic equation which is

it is the part inside of the square root part

it is called the discriminant beause it tells you how many real or complex roots/solutions you will get

so b^2-4ac

convert to ax^2+bx+c=0 form

9x^2+2=10x

subtract 10x

9x^2-10x+2=0

ax^2+bx+c=0

a=9

b=-10

c=2

substitute

-10^2-4(9)(2)

100-36(2)

100-72

28

discriminant is 28
