Question

Write the sum and the product of the roots of x^2+10x-5=0

Answer 1

$in \: a {x}^{2} + bx + c = 0 \\ sum \: of \: roots = \frac{ - b}{a} \\ product \: of \: roots = \frac{c}{a} \\ now \: in \: {x}^{2} + 10x - 5 = 0 \\ = > sum \: of \: roots = \frac{ - ( -10)}{1} = - 10 \\ = > product \: of \: roots = \frac{ - 5}{1} = - 5$
Hope it helps
