Heye

your answer⏬

_________________________

${x}^{2} - 3x - 10 \\ {x}^{2} - (5x + x) - 10 \\ {x}^{2} - 5x + 2x - 10 \\ x(x - 5) + 2(x - 5) \\ (x - 5)\: (x + 2) \\ x = 5 \\ x = - 2 \\ sum \: of \: zeroes \: \\ = \alpha \beta = 5 \times - 2 = - 10 \\ \alpha + \beta = \frac{ - b}{9} = - \frac{( - 3)}{1} = 3 \\ product \: of \: zeroes \: \\ = \alpha \beta = 5 \times - 2 = - 10 \\ \alpha \beta = \frac{c}{a} = \frac{ - 10}{1} = - 10 \\ proved \:$
