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

28.

Step-by-step explanation:

9x^2 + 2 = 10x

9x^2 - 10x + 2 = 0

The discriminant is b^2 - 4ac.

In this case, a = 9, b = -10, and c = 2.

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

= 100 - 36 * 2

= 100 - 72

= 28.

Since the discriminant is positive, there are two real solutions to the function.

Hope this helps!

step-by-step explanation:

assume that you have 3 different side lengths.   apply the pythagorean theorem here:   square each of the two shortest sides; call them a and b, so that their squares are a² and b².   also square the longest side, calling the result c².

now, if a² + b² = c² is true, the triangle is a right triangle; otherwise it is not a right triangle.
