ACTIVITY 1: Fill in the blanks to make each statement true
1.Any equation that can be written in the form \( a x^{2}+ \) \( b x+c=0 \), (where \( \mathrm{a}, \mathrm{b} \), and c are real numbers and \( a \neq 0 \) ) is called a/an \( \qquad \)
2.In the equation \( 9 x^{2}+4 x-8 \), a \( = \) \( \qquad \) , \( b= \) \( \qquad \) , and \( \mathrm{c}= \) \( \qquad \)
3. In the quadratic equation \( a x^{2}+b x+c=0, a \neq \) \( \qquad \)
4.The factored form of \( x^{2}-25 \) is \( \qquad \) .
5.If \( \mathrm{ab}=0 \), then \( \mathrm{a}= \) \( \qquad \) , \( b= \) \( \qquad \)
