Find the discriminant. r^2 + 2r + 1 = 0 ____

Identify values: Identify the values of a, b, and c by comparing the given equation r^2 + 2r + 1 = 0 with the standard quadratic equation form ax^2 + bx + c = 0. Here, a = 1, b = 2, and c = 1.Use discriminant formula: Use the discriminant formula D = b^2 - 4ac to find the discriminant of the quadratic equation. Substitute 1 for a, 2 for b, and 1 for c in the formula. D = (2)^2 - 4 * 1 * 1Calculate discriminant: Calculate the discriminant. D = 4 - 4 * 1 * 1 D = 4 - 4 D = 0

Q. Find the discriminant.

\newline

r^2 + 2r + 1 = 0

Identify values: Identify the values of $a$ , $b$ , and $c$ by comparing the given equation $r^2 + 2r + 1 = 0$ with the standard quadratic equation form $ax^2 + bx + c = 0$ . Here, $a = 1$ , $b = 2$ , and $c = 1$ .
Use discriminant formula: Use the discriminant formula $D = b^2 - 4ac$ to find the discriminant of the quadratic equation. $\newline$ Substitute $1$ for $a$ , $2$ for $b$ , and $1$ for $c$ in the formula. $\newline$ $D = (2)^2 - 4 \times 1 \times 1$
Calculate discriminant: Calculate the discriminant. $\newline$ $D = 4 - 4 \times 1 \times 1$ $\newline$ $D = 4 - 4$ $\newline$ $D = 0$
