2) Explain why the solutions to the two inequalities below are not the 8ame. \( \begin{array}{ll}\text { a. } x \geq 8 & \text { b. } x>7.9\end{array} \)

В ар иант 2 1. Преобразуйте в многочлен. а) \( (x-6)^{2} ; \)

Which expressions are equivalent to the given expression? \( 5 \log _{10} x+\log _{10} 20-\log _{10} 10 \)

uisl 3 a) \( x^{2}-12=0 \) b) \( 4 x^{2}-7 x=0 \) c) \( 6 x+12 x^{2}=0 \)

Find the value of \( m \) if \( \alpha+\beta=-2 \). (b) Seterusnya, bentukkan persamaan kuadratik dengan punca-punca \( \alpha \) dan \( \beta \). Hence, form a quadratic equation with roots \( \alpha \) and \( \beta \).

Enter the correct answer in the box. Rewrite the expression \( 2 \sqrt[4]{x^{7}} \) using rational exponents. \( \begin{array}{lll}\frac{\square}{\square} & \text { (ㅁ) } \mid \text { 미 } \square^{\square} \mid+--\end{array} \)
