Question

Find the discriminant: D=b^2-4acx^2-10x+25=0

Answer 1

The discriminant = 0

Step-by-step explanation:

The given equation is:

`x^2-10x+25=0`

Compare x² - 10x + 25 = 0 with ax² + bx + c = 0

a = 1, b = -10, c = 25

The discriminant is given by the formula:

`D=b^2-4ac`

Substitute a = 1, b = -10, c = 25 into the discriminant formula above

`\begin{gathered} D=(-10)^2-4(1)(25) \\ D=100-100 \\ D=0 \end{gathered}`

The discriminant = 0
