If A = \(\begin{bmatrix} 0 & 3\\ 0 & 0 \end{bmatrix}\)and f(x) = x+x2+x3+.....+x2023, then f(A)+I =
\(\begin{bmatrix} 0 & 0\\ 0 & 0 \end{bmatrix}\)
\(\begin{bmatrix} 1 & 3\\ 0 & 0 \end{bmatrix}\)
\(\begin{bmatrix} 1 & 3\\ 0 & 1 \end{bmatrix}\)
\(\begin{bmatrix} 1 & 3\\ 1 & 1 \end{bmatrix}\)
For \( n \in \mathbb{N} \), the largest positive integer that divides \( 81^n + 20n - 1 \) is \( k \). If \( S \) is the sum of all positive divisors of \( k \), then find \( S - k \).
A polynomial that has two roots or is of degree 2 is called a quadratic equation. The general form of a quadratic equation is y=ax²+bx+c. Here a≠0, b, and c are the real numbers.
Consider the following equation ax²+bx+c=0, where a≠0 and a, b, and c are real coefficients.
The solution of a quadratic equation can be found using the formula, x=((-b±√(b²-4ac))/2a)
