Step 1
For the equation \( a^{2}+8 a+12=(a+2)(a+\square) \), we need to find a number that when multiplied with \(a+2\) gives \(a^{2}+8 a+12\). The missing term is 6 because \(6*(a+2) = a^{2}+8 a+12\). Show more…

Which of the following is equivalent to the sum of the expressions $a^{2}-1$ and $a+1 ?$ \begin{equation} \begin{array}{l}{\text { A) } a^{2}+a} \\ {\text { B) } a^{3}-1} \\ {\text { C) } 2 a^{2}} \\ {\text { D) } a^{3}}\end{array} \end{equation}
Let $a_{1}, a_{2}, a_{3}, \ldots$ be terms of an A.P. If $\frac{a_{1}+a_{2}+\ldots a_{p}}{a_{1}+a_{2} \ldots+a_{q}}$ $=\frac{p^{2}}{q^{2}}, p \neq q$, then $\frac{a_{6}}{a_{21}}$ equals $\quad$ [2006] (A) $\frac{41}{11}$ (B) $\frac{7}{2}$ (C) $\frac{2}{7}$ (D) $\frac{11}{41}$
perform the indicated operations for each expression, if possible. $$A=\left[\begin{array}{rrr}-1 & 3 & 0 \\2 & 4 & 1\end{array}\right] \quad B=\left[\begin{array}{rr}0 & 2 & 1 \\3 & -2 & 4\end{array}\right] \quad C=\left[\begin{array}{rr}0 & 1 \\2 & -1 \\3 & 1 \end{array}\right] \quad D=\left[\begin{array}{rr}2 & -3 \\0 & 1 \\4 & -2 \end{array}\right]$$ $$E=\left[\begin{array}{rrr}-1 & 0 & 1 \\2 & 1 & 4 \\-3 & 1 & 5 \end{array}\right] \quad F=\left[\begin{array}{r}1 \\0 \\-1\end{array}\right] \quad G=\left[\begin{array}{ll}1 & 2 \\3 & 4\end{array}\right]$$ $$(A+E) D$$
