Answer 2

Step-by-step explanation:

$</p><p>\begin{gathered}let \: \alpha \: = 3 \\ \: \: \: \: \: \beta \: = 5 \: \\ \alpha \beta \: = \ c \div a \\ 15 = \: \: c\div a\\ here \: a \: = 1 \: \\ \: \: \: \: \: \: \: \: \: \: c \: = 15 \\ \\ \\ \alpha + \beta = - b \div a \\ 3 + 5 = - b \div a \\ 8 = - b \div a \\ here \: a = 1 \: .b = - 8 \\ \end{gathered}letα=3β=5αβ= c÷a15=c÷aherea=1c=15α+β=−b÷a3+5=−b÷a8=−b÷aherea=1.b=−8</p><p>Put all these value in General equations</p><p>ax²+by+c =0</p><p>1x² -8y+ 15 =0</p><p>$
