Question

can any one answer me the second on of polynomial.plz

Answer 1

for infinite number of solutions
$\frac{a1}{a2} = \frac{b1}{b2} = \frac{c1}{c2} \\ \frac{k}{16} = \frac{4}{k} = \frac{k - 4}{k} \\ {k}^{2} = 64 \\ k = + - 8 \: \: - (1) \\ \frac{4}{k} = \frac{k - 4}{k} \\ 4k = {k}^{2} - 4k \\ 8k = {k }^{2} \\ k = 0 \: and \: 8 \: \: - (2) \\ from \: (1) \: and \: (2) \: \\ k = 8$
