Question

say the answer please​

Answer 1

$x^{2} - 5x + 6 \\ x^{2} - 3x - 2x + 6 \\ x(x - 3) - 2(x - 3) \\ (x - 2)(x - 3) = 0 \\ x = 3 \: or \: x = 2 \\ \\ \alpha + \beta = - b \div a = - ( - 5) \div 1 = 5 \\ \alpha + \beta = - 3 - 2 = - 5 \\ \alpha \beta = c \div a = 6 \div 1 \\ \alpha \beta = - 3 \times - 2 = 6 \\ hence \: verified$
