0. Tye algebraic expressions are given below. \[ \left(2 x^{2}+7 x-4\right) \text { and }(x-3) \] xat Divide \( \left(2 x^{2}+7 x-4\right) \) by \( (x-3) \) (b) For what value replaced in 4 of the above expression, the remainder is equal to 0 ?

\( \left. \begin{array} { l } { ( x + y ) ^ { 3 } = z } \\ { ( y + z ) ^ { 3 } = x } \\ { ( z + x ) ^ { 3 } = y } \end{array} \right. \)

\( k+9, k-6 \) र 4 एउटा गुणोत्तर अनुक्रमका \( k+9, k-6 \) and 4 are the three terms of a geometric progression (i) \( k \) को मान पत्ता लगाउनुहोस् । (Find the value of \( k \).) (ii) समान अनुपात पत्ता लगाउनुहोस् । (Find the common ratio.) (iii) चौथो पद पत्ता लगाउनुहोस् । (Find the value of fourth term.) odel 3 Problems based on finding the position of a given term i)

What does the exponent in an expression indicate?

Calcula \( X \) tal que \( X-B^{2}=A \cdot B \), siendo que: \[ A=\left(\begin{array}{lll}1 & 0 & 1 \\ 1 & 1 & 0 \\ 0 & 0 & 2\end{array}\right), \quad B=\left(\begin{array}{ccc}1 & 0 & -1 \\ 1 & 1 & 1 \\ 0 & 0 & 1\end{array}\right) \]

Cho hàm số \( f x=\left\{\begin{array}{ll}\frac{\sqrt{4 x+1-1}}{a x^{2}+(2 a+1) x 0} & \text { khi } x \neq 0 \\ 3 & k h i \quad x=0\end{array}\right. \). Biết rằng \( a \) là giá trị đề hàm số liên tu \( =0 \), hãy tìm số nghiệm nguyên của bất phương trình \( x^{2}-x+36 a<0 \).
