Question

find the value of k if the sum of roots of x²-kx+2x-4=10 plz faster​

Answer 1

Answer:

k=12 see the right answer above

Answer 2

${x}^{2} - x(k - 2) - 4 = 0 \\ \\ a = 1 \\ b = - (k - 2) \\ c = - 4 \\ \\ sum \: of \: roots = \frac{ - b}{a} \\ = \frac{ - ( - k + 2)}{1} = k - 2 \\ \\ acc \: to \: you \: sum \: of \: roots = 10 \\ \\ k - 2 = 10 \\ \\ k = 12$
