What is the discriminate of 9x^2 + 2=10x

28

Step-by-step explanation:

Move the 10x to the other side of the equal sign by subtracting it from both sides.

9x^2 + 2 - 10 = 0

Plug the numbers into the formula b^2 - 4 (ac)

Substitute in the values of a, b, and c.

( - 10) ^2 - 4 (9 ⋅ 2)

Simplify each term until it cant be reduced anymore

28

Step-by-step explanation:

The discriminate of ax² + bx + c:

D = b² - 4ac

We have the equation: 9x² + 2 = 10x subtract 10x from both sides

9x² - 10x + 2 = 0

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

Substitute:

D = (-10) ² - 4 (9) (2) = 100 - 72 = 28
