The problem is asking for the value of \( m \) such that the function \( f(x) = x^2 + 10x + (m - 1) \) is tangent to the x-axis.

For a quadratic function \( f(x) = ax^2 + bx + c \) to be tangent to the x-axis, its discriminant must be zero. The discriminant \( \Delta \) of a quadratic equation \( ax^2 + bx + c = 0 \) is given by:

\[
\Delta = b^2 - 4ac
\]

In this case:
- \( a = 1 \) (the coefficient of \( x^2 \)),
- \( b = 10 \) (the coefficient of \( x \)),
- \( c = m - 1 \) (the constant term).

Using the discriminant formula, we set the discriminant to

Agar kurva fungsi f(x) = x^2 + 10x + (m - 1) menyinggung sumbu x, maka nilai m yang mungkin adalah?

Learn how to solve the quadratic function f(x) = x^2 + 10x + (m - 1) and find the value of m for which the curve is tangent to the x-axis using the discriminant formula. This example is ideal for students in Grades 9-12.
