Question

which of the following quadratic equations has roots 3,5

Answer 1

$let \: \alpha \: = 3 \\ \: \: \: \: \: \beta \: = 5 \: \\ \alpha \beta \: = \ c \div a \\ 15 = \: \: c\div a\\ here \: a \: = 1 \: \\ \: \: \: \: \: \: \: \: \: \: c \: = 15 \\ \\ \\ \alpha + \beta = - b \div a \\ 3 + 5 = - b \div a \\ 8 = - b \div a \\ here \: a = 1 \: .b = - 8$
Put all these value in General equations
ax²+by+c =0
1x² -8y+ 15 =0
